This post is all about different aspects photographing lightning—some of the stuff I write about here is covered in much more detail in my Lightning Photo Tips article, so you might want to start there
I’ve been photographing lightning at the Grand Canyon (especially) and elsewhere for 10 years, but I’m happy to say that I’m still learning. While going through my images from this year’s recently completed Grand Canyon monsoon workshops, it occurred to me that now might be a good time to share a couple of this year’s insights.
Lightning Trigger (where it all begins)
You simply can’t photograph daylight lightning consistently without a lightning sensor that detects the lightning and triggers your shutter. And if you follow my lightning photography at all, you’ve no doubt heard me singing the praises of the Lightning Trigger from Stepping Stone Products in Colorado. (There are a lot of lightning sensors out there, but since Lightning Trigger is trademarked, this is the only one that can legally use “lightning trigger.”) I don’t get anything from Stepping Stone for my endorsement, I just know it’s in my best interests to give everyone in my groups the best chance to photograph lightning, and so far I haven’t found anything that comes close the the success of the Lightning Trigger.
But despite my strong advice to the contrary, every year one or two people will show up with a sensor that’s not a Lightning Trigger. And every year, these are the people who have the poorest lightning success. Sometimes the reason for failure is obvious—like a sensor that allowed the camera to go to sleep after 30 seconds of inactivity. But usually the reason isn’t quite so obvious—I just know that the people with the “other” sensors are much more likely to get shut out. This year was no exception.
The first workshop (of three) started with a bang, with an active storm building across the canyon, about 12 miles away, just before the workshop orientation. Because lightning trumps everything in these monsoon workshops, I cancelled the orientation and herded everyone to the view deck behind Grand Canyon Lodge (I’d advised them to show up with their gear for this very reason), frantically flying around from person to person to introduce myself, help them set up, and make sure their cameras were clicking with each lightning strike.
After about 15 minutes, all but one seemed comfortably settled in, excitedly reporting that their camera was responding to each bolt. In addition to my one participant who wasn’t having success, there was a woman who wasn’t in my group trying to photograph lightning with a sensor—she too was growing frustrate because her camera seemed be ignoring the lightning too. The one thing these two people had in common? Perhaps you already guessed: they were the only two not using a Lightning Trigger.
I actually tried to help both of them troubleshoot the problem, starting with confirming that everything was plugged in right, then quickly moving to lots of fiddling with camera settings, cables, and batteries. But since I could make their sensors respond with the TV remote I always have nearby when I photograph lightning (the easiest way to test a Lightning Trigger in the field), I wasn’t real optimistic—if the remote triggers the camera, the problem is unlikely to be the connection, power, or camera. That leaves the sensor itself as the most likely culprit.
When leading a workshop I don’t have lots of time to get too scientific with my troubleshooting, but think I solved the mystery the next day, when a similar storm started up at about the same time in more less the same place. For the second day in a row we all set up on the Grand Canyon Lodge view deck, and for the second day in a row, the only person in the group whose camera wasn’t responding was the person with the off-brand sensor. (The woman from the prior day wasn’t there.)
While the prior day’s storm moved laterally across the canyon, this storm moved in our direction, approaching to within a couple of miles (and eventually driving us all for cover in the lodge). When, as the storm got closer, the rogue sensor started triggering its camera, I realized that what sets the Lightning Trigger apart from its competition is most likely its range.
My superior range theory got more confirmation on the South Rim a couple of days later. Driving out toward the South Rim’s eastern-most views for our sunset shoot, my eyes were drawn to a massive thunderhead blooming in the distance. With the forecast offering no hope for lightning to chase, that evening’s plan was to make a couple of quick stops at Lipan and Navajo Points, before finishing with sunset at Desert View. But pulling into Lipan Point it was instantly apparent that the thunderhead was straight up the canyon—we weren’t there long before we could also see it was delivering lightning. (One reason I tell everyone to always carry their Trigger, regardless of the forecast.)
Because this turned out to be a spectacular show that lasted until sunset, we never left Lipan Point. Unlike the previous storms, where the lightning was front-and-center in every composition, the lightning this evening was much farther away—between 22 and 25 miles distant, according to the My Lightning Tracker app on my iPhone. While all the Lightning Triggers didn’t seem to miss a single bolt (“not missing” in this case just means firing when there’s a visible bolt—you’ll see below that this is by no means a guarantee that the bolt will be capture), our rogue sensor not seem to see the lightning at all.
Further confirmation of the Lightning Trigger’s range came in the third workshop, when we were photographing lightning more than 30 miles away. I’ve had success with the Lightning Trigger and distant lightning in the past, but this was the first time I’ve had an app (and cellular connectivity) to actually pinpoint the location and distance.
Slower than the speed of lightning (or, About this image)
One of the most frustrating things about photographing lightning is not capturing a spectacular strike. The first half of the capture equation is a sensor that sees the lightning and triggers the camera (see Lightning Trigger discussion above); the other half is having a camera that responds quickly enough to the click instruction from the sensor. And as I’ve said before, all the three major camera brands are fast enough, but where lightning is concerned, the faster the better—and it’s impossible to be too fast. FYI, according to Imagining Resource, Sony Alpha camera’s are the fastest, followed closely by Nikon, with Canon a fair amount slower (but usually not too slow).
I can confirm the Imaging Resource data. While I had good success while using Canon my first few years photographing lightning, my success rate has been noticeably higher since switching to Sony in 2014 (my first Sony lightning shoot was in 2015). But despite a faster camera, the frustration with missed lightning hasn’t disappeared completely. Usually it’s just one or two here and there—I just shrug my shoulders because I know I’ll probably get the next one. But in this year’s third workshop, one especially frustrating shoot got my attention.
The third group didn’t have any lightning luck on the North Rim for our first two days, but the forecast looked more promising for the South Rim half of the workshop. Unfortunately, the best chances were forecast for the day of our 4-hour rim-to-rim drive. Since it’s such a nice drive, I usually give everyone the whole day to make it, suggesting stops then setting them free after the sunrise shoot—we don’t gather as a group again until late afternoon on the other side. But with such a promising lightning forecast, this time I had everyone meet me at Desert View, the first South Rim vista when driving from the North Rim, at 1:00 p.m., hoping that we’d get the workshop’s first shot at lightning.
Setting up on the rim just west of the Desert View Watchtower, we just hung out for awhile, waiting for something to happen. Our patience was rewarded after about an hour, when a few people in the group saw lightning in the east. This was out toward the Painted Desert—not actually over the canyon, but close enough to get lightning and the canyon in one frame. Better yet, it soon became clear that the storm was moving, not just toward the canyon, but toward one of my favorite Grand Canyon views.
This whole shoot lasted at least a couple of hours. Standing there on the rim, we watched the lightning first migrate north, eventually intersecting the canyon just beyond the Little Colorado River confluence. It then started to shift westward, crossed the canyon, continued drifting west, and everyone was pretty excited. That is, until we realized that it was also getting closer. We were preparing to retreat when a bolt hit inside the canyon, less than two miles away, sending our sense of urgency into overdrive.
Since this was this group’s first lightning, everyone was especially excited when their camera clicked with each lightning bolt. Though I knew no one would get every single bolt, with several dozen visible strikes, I was pretty confident everyone’s success numbers would be in the double digits—mine included.
But checking my images in my room that night, I was disappointed to count only three frames with lightning. I was just going to write it off as one of those things—perhaps my LT battery was weak, or maybe I was too focused on working with others in the group (in other words, doing my job) to adjust my composition frequently enough to track the continuously shifting storm.
But when I mentioned my poor success to Curt, my assistant on this trip, he expressed similar results. And talking to the group the next day, we learned that no one else got more than a (very small) handful of strikes. How could a dozen people using a lightning sensor that years of experience proves works reliably, on a variety of cameras, have such similarly poor results on just one shoot? Adding to the mystery, it became clear by the images shared in the image review that the lightning everyone did capture, was all the same strikes. What’s going on?
One of the things I love most about working with Curt is that he’s as inquisitive and bulldog-tenacious tracking down these mysteries as I am. We got to work researching what could be going on, both on our own, and together on a one-hour conference call with Rich at Stepping Stone, the mastermind behind the Lightning Trigger.
Rich suggested that it could be that we encountered a storm that was mostly positive lightning. Positive lightning, which comprises about 5 percent of lightning strikes, usually spends all of its energy in a single stroke, making that one stroke very bright, but also much faster from start to finish. He thought that maybe the lighting was done before everyone’s cameras could react. That made sense.
But after a little research on positive lightning, I (tentatively) ruled it out as our culprit because: 1) I saw nothing that indicates that positive lightning is storm-specific (though I’m open to correction); 2) positive lightning originates near the top of the cloud, and I saw no sign of that in this storm; 3) positive lightning tends to come near the end of the storm, and we photographed this one from start to finish; and finally, 4) positive lightning typically strikes outside the main rain band, and we saw very little of this.
But that conversation with Rich convinced me that our problem this afternoon had to indeed be a caused by lightning that was too fast for our cameras. And after mulling that thought for awhile, then digging deeper into my lightning resources, I theorized that we’d probably just encountered a storm that didn’t have as much juice as the typical monsoon storms I’m accustomed to.
This makes sense if you understand that a typical negative lightning strike that looks like a single bolt to the eye (or camera), is actually a series of strokes following the same channel. The number of strokes in a single lightning bolt varies with the amount of energy the lightning needs to release—the more strokes, the longer the strike seems to last. (As an interesting aside, earlier in the trip Curt got accidental confirmation of lightning’s multiple stroke aspect when, with his camera set to Continuous rather than the Single Shot that I use, he got the same lightning bolt in two, and at least once, three contiguous frames.)
The jury is still out on this theory, but it makes sense. If I learn anything more, I promise to share it. Right now I’m in the process of updating the Lightning Photo Tips article with this and more insights gained since the last update, so that’s the best place to check for new information.
Oh, and the image I share here was one of my three successes that afternoon, so I’m not really complaining.

This week I’m at the Grand Canyon with virtually no connectivity, so I dug up this blog post from one of the most memorable photography experiences of my life.
Nature photographers plan, and plan, and plan some more, but no amount of planning can overcome the fickle whims of Mother Nature. Few things are more disappointing than a long anticipated and perfectly executed shoot washed out by conditions beyond my control. But when all of nature’s variables click into place, the world becomes a happy place indeed. And when nature ups the ante by adding something unexpected, euphoria ensues.
Don Smith and I just returned from two weeks photographing the Grand Canyon. We did a little of our own photography on the trip, but the prime focus was our two four-plus day photo workshops, split evenly between the Grand Canyon’s North and South Rims. These workshops were scheduled to give our groups the opportunity to photograph the Grand Canyon, day and night, under the influence of the annual Southwest monsoon: billowing clouds, vivid rainbows, and (especially) lightning. But any workshop requiring specific weather conditions is fraught with uncertainty and anxiety—we were fairly certain the photography would be great (after all, it is the Grand Canyon), but few natural phenomena are more fickle than lightning.
When plotting a workshop schedule (or any landscape photo shoot), the best a photographer can do is maximize the odds: We try to schedule all the non-photography requirements (meals, sleep, travel, training) for the times least likely to conflict with the best photography. For example, we know that because the monsoon thunderstorms usually don’t develop before midday, Grand Canyon summer sunrises often lack the clouds and pristine air necessary for the vivid color photographer’s covet. Therefore our photography emphasis for this workshop is on getting our groups out from mid-morning through (and sometimes after) sunset. That doesn’t mean we blow off sunrise, it just means that the sunrises are generally better for exhausted, sleep-deprived photographers to skip than the sunsets are.
Nevertheless, we rallied the troops at 5 a.m. Friday for our second workshop’s final shoot, a ten minute walk from our rim-side cabins to Bright Angel Point. The forecast was for clear skies, but the workshop had already had so many wonderful shoots, I considered this final one just a little bonus, the cherry atop an already delicious sundae.
My mind was already on the long drive home—in fact, as Don and I exited our cabin in the pre-dawn darkness, I predicted that I wouldn’t even take my camera out of my bag that morning. My words as I turned the doorknob were, “But if I leave my bag here, we’ll probably get lightning and a rainbow.” Little did I know how grateful I’d be to have brought my gear….
What followed was what Don and I later agreed was probably the single most memorable workshop shoot either of us had ever experienced. Gathering in the lobby of Grand Canyon Lodge, we saw lightning flashes across the canyon, but it was impossible to tell in the darkness how far away it was. Hiking to the vista, we saw several distinct bolts stab the rim, and by the time our gear was set up, the show had intensified, delivering numerous violent strikes in multiple directions that illuminated the canyon several times per minute.
The morning’s pyrotechnics continued for over two hours, awing us first in the dark, then through twilight, and finally into and beyond a magenta sunrise. And as if that wasn’t enough, as the sun crested the horizon behind us, a small but vivid fragment of rainbow materialized on the canyon’s rim, hanging there like a target for the lightning to take potshots at it.
This was more than just good photography, this was a once-in-a-lifetime convergence of weather, location, and light that more than made up for the many times nature has disappointed. Rather than bore you with more words, here are a few images from that morning:

Greetings from the Grand Canyon. It’s pretty hard to post a blog in the middle of a workshop, and downright near impossible when the Internet is down and your cellular carrier has capped your roaming data at 200 megabytes (which I ripped through in 3 days, with only 12 days to go—thank you very much, T-Mobile). But here I am, a day late, with some thoughts on improving your lightning photography and an update on the Grand Canyon monsoon activity so far.
Subtracting one year lost to COVID, this is my eighth year doing at least two monsoon workshops at the Grand Canyon—this year it’s three. In previous years I’ve done these workshops in partnership with my friend and fellow Sony Artisan Don Smith; this year I’m flying solo, grateful for the assistance of my friend (photographer, sensor cleaning guru, and essential lightning tracker) Curt Fargo.
Being solely responsible for the success and wellbeing of a dozen photographers isn’t without its stress. Despite the always breathtaking beauty that comes with the Grand Canyon monsoon, make no mistake about it: people sign up for these workshops for the lightning. And while I make it very clear that enrollment comes with no guarantees, and do my absolute best to prepare everyone well in advance, I still stress until each person in my group has captured at least one bolt.
Many factors contribute to lightning success, but when you measure success by the results of a dozen other people, things get even more complicated. And since we’re in the midst of lightning season for most of the Northern Hemisphere, I thought I’d share my thoughts on maximizing lightning success. In no particular order, here are my essential lightning preparation tips:
I do my best to fill my groups with all this knowledge and more, before we start. Even though we’ve been been shut out a few times, I’ll take a little credit for the overall success rate—so far my workshop lightning batting average (everyone in the workshop gets at least one strike) is probably somewhere around .700, and in a few workshops some, or even most, had a success.
But really, regardless of the preparation, the biggest factor in capturing lightning in a workshop that was scheduled more than a year in advance, comes down to just plain luck, and like all weather phenomena, lighting is random. But preparation does give you the best possible chance of success if you’re lucky enough to get a chance. And honestly, it’s the unknown that makes chasing lightning so much fun.
Read my complete lightning photography how-to guide in my Photo Tips Lightning article.
Back to the present
This morning I wrapped up the first of three consecutive Grand Canyon monsoon workshops. To say that we started with a bang would be an understatement. For just the second time since I started doing this, we postponed our 1 p.m. orientation because the lightning started around noon. Fortunately, a couple of days before our start I’d sent an e-mail letting everyone know this was possible, and to show up at the orientation with gear and prepared to hit the ground running. And that’s what we did.
For the workshop’s first two hours, we photographed a very active electrical storm across the canyon from our North Rim perch at Grand Canyon Lodge. By the time we were done, I’d captured 35 frames with lightning, only one person in the group didn’t have at least one lightning strike (most had many more)—the person who showed up with a lightning sensor that wasn’t a Lightning Trigger.
The next day we got our morning shoot and training session in, but the afternoon training session was almost immediately preempted by another crazy lightning storm. This storm started fairly mild, then intensified as it moved much closer and eventually chased us inside. This time everyone captured multiple lightning strikes, which makes me think that one of the things that distinguishes the Lightning Trigger from the other brands is its range. But whatever the reason, I could finally relax.
Of course throughout the workshop we photographed a lot of nice stuff that wasn’t lightning, so by our last night I think everyone was pretty satisfied with their bounty. Which of course didn’t prevent us from being greedy. Departing for our final sunset with low expectations, we were instead treated to maybe the best show of the workshop. This storm wasn’t as prolific as the earlier two, and the lightning was more than 20 miles away, but it happened above some of my favorite Grand Canyon scenery, and was accompanied by a towering thunderhead, beautiful sunset color, and a massive rain curtain to catch the sunset color and light.
I wish I could tell you that I have photographic proof of all this drama to share right now, but I’ve been just a little busy. So I’m sharing the only image from the workshop that I’ve processed so far. This V-shaped pair came toward the end of the first afternoon’s storm, and while I’m always happy to get multiple lighting bolts in one frame, I’m pretty sure I ended up with captures I like even better. But we’ll just have to wait…

Ten days ago my brother and I drove to the Grand Canyon to photograph the monsoon—you can read the story of our trip in my previous blog post.
I don’t get tired of photographing lightning. My brother Jay and I timed last month’s trip because the forecast promised lots of lightning, and though we did indeed see a lot of lightning, most of it was actually too close to photograph. Each day Jay and I headed out right after breakfast, stayed out most of the day, and returned to our room around dinnertime with lots of nice images, but no lighting to show for our effort.
I like to stand on the rim of the Grand Canyon and photograph lightning up, down, or across the canyon, but most of the lightning we saw was either coming up behind us, or right on top of us. The frustrating reality of lightning photography is that when there’s too much, it’s usually too close. How close? Fixing dinner one evening, we saw a bolt hit about 50 yards from our room. And one afternoon on the rim, while watching a storm approach from the south and hoping it would hold together long enough to make it over the canyon, I reached to adjust my camera and got a shock—we were back in the car within five seconds.
Given all the lightning we dodged on the South Rim, had we been on the North Rim, we’d have had a field day—but on the South Rim, all we got was wet. Despite our frustration, on our last day the forecast was again promising, so we went back out filled with optimism. As we had on our previous days, we pointed our cameras at lots of promising cells with no success. Lots of dry frames—shutter clicks when the Lightning Trigger detects lightning that wasn’t visible or in my frame (I could have turned down the sensitivity, but don’t usually do that until I’ve had some success)—but just one meh lightning strike I knew I’d never process. That’s just the way lighting photography goes.
But I’m nothing if not persistent, which is how we found ourselves out near Lipan Point late that final afternoon. Despite our lack of lightning success, we’d had a lot of the otherwise spectacular photography that the monsoon often delivers—billowing clouds, dark curtains of rain, light shafts, dappled light, and gorgeous sunset color—and this afternoon was no exception. I was composed on a broad area of falling rain that looked moderately promising, resigned to the fact that it too would probably fizzle (but nevertheless appreciating the gorgeous light and clouds), when a single bolt fired across the canyon. It caught me so off guard that I almost didn’t believe it, but I heard my camera click and Jay exclaim, so I marked the frame (took a picture of my hand to make it easier to find among the hundreds of empty frames) and crossed my fingers.
We saw two more lightning bolts that afternoon, but this turned out to be the only one I deemed worthy of processing. On the drive home Jay and I agreed that our trip was a great success—while we didn’t get as much lightning as we’d have liked, we got lots (and lots) of beautiful storm images, photographed a vivid sunset, and had two great Comet NEOWISE shoots. This lighting strike on our final afternoon was simply icing on the cake.
Below is the just updated (August 2, 2020) Lightning article from my Photo Tips section
Few things in nature are more dramatic than lightning. Or more dangerous. And if “safety first” is a criterion for intelligence, photographers are stupid. Because lightning is both dangerous and unpredictable, the more you understand lightning, how to anticipate it and stay safe in its presence, the greater your odds of surviving to take more pictures.
The shocking truth about lightning
A lightning bolt is an atmospheric manifestation of the truism that opposites attract. In nature, we get a spark when two oppositely charged objects come in close proximity. For example, when you get shocked touching a doorknob, on a very small scale, you’ve been struck by lightning.
In a thunderstorm, the up/down flow of atmospheric convection creates turbulence that knocks together airborne molecules, stripping their (negatively charged) electrons. Lighter, positively charged molecules are carried upward in the convection’s updrafts, while the heavier negatively charged molecules remain near the bottom of the cloud. Soon the cloud is electrically polarized, more positively charged at the top than at the base.
Nature always takes the easiest path—if the easiest path to electrical equilibrium is between the cloud top and bottom, we get intracloud lightning; if it’s between two different clouds, we get intercloud lightning. Less frequent cloud-to-ground strikes occur when the easiest path to equilibrium is between the cloud and ground.
With lightning comes thunder, the sound of air expanding explosively when heated by a 50,000-degree jolt of electricity. Thunder travels at the speed of sound, a pedestrian 750 miles per hour, while lightning’s flash zips along at the speed of light, more than 186,000 miles per second—nearly a million times faster than sound.
Knowing that the thunder occurred at the same time as the lightning flash, and the speed both travel, we can calculate the approximate distance of the lightning strike. While we see the lightning instantaneously, thunder takes about five seconds to cover a mile: Dividing by 5 the number of seconds between the lightning’s flash and the thunder’s crash gives you the lightning’s distance in miles (divide by three for kilometers).
The 30 (or so) people killed by lightning in the United States each year had one thing in common with you and me: they didn’t believe they’d be struck by lightning when they started whatever it was they were doing when they were struck. The only sure way to be safe in an electrical storm is to be in a fully enclosed structure or metal-framed vehicle, away from open windows, plumbing, wiring, and electronics.
Unfortunately, photographing lightning usually requires being outside. And though there’s no completely safe way to photograph lightning, it doesn’t hurt to improve your odds of surviving enough to enjoy the fruits of your labor.
Most lightning strikes within a ten-mile radius of the previous strike. So, if less than thirty seconds elapses between the flash and bang, you’re too close. And since “most” doesn’t mean “all,” it’s even better to allow a little margin for error. Thunder isn’t usually audible beyond ten miles—if you can hear the thunder, it’s safe to assume that you’re in lightning range.
But if you absolutely, positively must be outside with the lightning firing about you, or you simply find yourself caught outside with no available shelter, there are few things you can do to reduce the chance you’ll be struck:
The thousands of humans killed by lightning each year had one thing in common with you and me: none believed they’d be struck by lightning. The safest place in an electrical storm is a fully enclosed structure or metal-framed vehicle (it has nothing to do with the tires), windows closed, away from windows, plumbing, wiring, and electronics.
The surest way to be struck by lightning is to be outside in an electrical storm, but photographing lightning usually requires being outside. And while there’s no completely safe way to photograph lightning, it doesn’t hurt to improve your odds of surviving.
Most lightning strikes within a six-mile radius of the previous strike, but strikes have been known to happen much farther from the storm. Since thunder isn’t usually audible beyond ten miles, if you hear thunder, you should go inside and stay there until at least 30 minutes after the thunder stops.
If you absolutely must be outside with lightning nearby, or you simply find yourself caught outside with no available shelter, there are things you should know and do to be safer:
If, after factoring in all the risks, you still like the idea of photographing lightning, you need to gear up. The extreme contrast between darkness and brilliant lightning means photographing lightning at night is mostly a matter of pointing your camera in the right direction with a multi-second shutter speed and hoping the lightning fires while your shutter’s open—pretty straightforward.
Photographing daylight lightning is more problematic. It’s usually over before you can react, so any success just watching and clicking is probably dumb luck. And using a neutral density filter to stretch the exposure time out to multiple seconds sounds great in theory, but in daylight, a lightning bolt with a life measured in milliseconds, captured in an exposure measured in seconds, will almost certainly lack the contrast necessary to show up in an image.
Lightning Trigger: The best tool for the job
Most lightning sensors (all?) attach to your camera’s hot shoe and connect via a special cable to the camera’s remote-release port. When engaged, the sensor fires the shutter (virtually) immediately upon detecting lightning, whether or not the lightning is visible to the eye or camera. With so many lightning sensors from which to choose, I did lots of research before buying my first one. I ended up choosing the sensor that was the consensus choice among photographers I know and trust: Lightning Trigger from Stepping Stone Products in Dolores, CO. At around $350 (including the cable), the Lightning Trigger is not the cheapest option, but after many years leading lightning-oriented photo workshops, I can say with lots of confidence that lightning sensors are not generic products, and the internal technology matters a lot. Based on my own results and observations, the Lightning Trigger is the only one I’d use and recommend (I get no kickback for this). On the other hand, if you already have a lightning sensor you’re happy with, there’s no reason to switch.
I won’t get into lots of specifics about how to set up the Lightning Trigger because it’s simple and covered fairly well in the included documentation. But you should know that of the things that sets the Lightning Trigger apart from many others is its ability to put your camera in the “shutter half pressed” mode, which greatly reduces shutter lag (see below). But that also means that connecting the Trigger will probably disable your LCD replay, so you won’t be able to review your captures without disconnecting—a simple but sometimes inconvenient task. You also probably won’t be able to adjust your exposure with the Lightning Trigger connected.
The Lightning Trigger documentation promises a range of at least a 20 mile, and after using mine at the Grand Canyon for years, I’ve seen nothing that causes me to question that—if anything, without actually testing it, I’d guess that its range is at least 30 miles. The LT documentation also says you can expect the sensor to fire at lightning that’s not necessarily in front of you, or lightning you can’t see at all, which I will definitely confirm. For every click with lightning in my camera’s field of view, I get many clicks caused by lightning I didn’t see, or that were outside my camera’s field of view. But when visible lightning does fire somewhere in my composition, I estimate that the Lightning Trigger clicked the shutter at least 95 percent of the time (that is, even though I got lots of false positives, the Lightning Trigger missed very few bolts it should have detected). Of these successful clicks, I actually captured lightning in at least 2/3 of the frames.
The misses are a function of the timing between lightning and camera—sometimes the lightning is just too fast for the camera’s shutter lag. In general, the more violent the storm, the greater the likelihood of bolts of longer duration, and multiple strokes that are easier to capture. And my success rate has increased significantly since switching from a Canon 5DIII to the much faster Sony Alpha bodies (more on this in the Shutter Lag section).
The Lightning Trigger documentation recommends shutter speeds between 1/4 and 1/20 second—shutter speeds faster than 1/20 second risk completing the exposure before all of the secondary strokes fire; slower shutter speeds tend to wash out the lightning. To achieve daylight shutter speeds between 1/4 and 1/20 second, I use a polarizer and usually set my ISO to 50 and aperture to f/16 or smaller. Of course exposure values will vary with the amount of light available, and you may not need such extreme settings when shooting into an extremely dark sky. The two stops of light lost to a polarizer helps a lot, and 4- or 6-stop neutral density filter is even better with fairly bright skies (but if you’re using a neutral density filter, try to avoid shutter speeds longer than 1/4 second).
Lightning is fast, really, really fast, so the faster your camera’s shutter responds after getting the command to fire, the more success you’ll have. The delay between the click instruction (whether from your finger pressing the shutter button, a remote release, or a lightning sensor) and the shutter firing is called “shutter lag.”
In general, interchangeable lens cameras (mirrorless and DSLR) have the fastest shutter lag. But even with an ILC, it’s surprising how much shutter lag varies from manufacturer to manufacturer, and even between models from the same manufacturer.
Ideally, your camera’s shutter lag should be 60 milliseconds (.06 seconds) or faster, but 120 milliseconds (.12 seconds) is usually fast enough. Most of the top cameras from Sony, Nikon, and Canon are fast enough—currently, Sonys are fastest, Nikon is a close second, and Canon is third.
And shutter lag can vary with the manufacturer’s model: While my Sony a7RIV may be the fastest camera out there, my original a7R was unusably slow, so you need to check your model’s shutter lag.
Unfortunately, shutter lag isn’t usually in the manufacturers’ specifications. The best source I’ve found is the “Pre-focused” time in the Performance tab of the camera reviews at Imaging Resource.
In addition to a lightning sensor and fast camera, you’ll need:
I’ve used a few lightning apps, but I finally think I’ve found one worthy of recommending: My Lightning Tracker. I have the “pro” version, which just means I paid a few dollars so I don’t have to see ads. This app has too many useful features to list here, but the most important thing it does is give me a good idea where the lightning is firing now (as long as I have a cellular or wifi connection), and how far away it is. It will also alert me of any strikes within a user-specified radius. It’s easy to use and seems to be reliable.
Getting the shot
Even if you can photograph lightning from your front porch, it’s usually best to pick a nice scene, then monitor the weather so you can be there to capture lightning with a great foreground. I strongly recommend that you scout these lightning scenes in advance, not just for possible compositions, but for safe places to set up, escape routes, and a place to retreat to if the lightning gets too close. I try never to shoot more than a quick sprint from my car.
Once you’re there, don’t wait until you see lightning before setting up your gear. If the sky looks even a little promising, get everything ready: tripod out, camera and lens mounted, lightning sensor attached. Then test your lightning sensor to make sure it fires your camera—I can’t tell you how easy it is to overlook one little thing and wonder why the lightning is firing but your camera isn’t. I test my Lightning Triggers, with a TV remote, or with the flash from my iPhone camera.
As I said earlier, the trickiest part of lightning photography is getting the right shutter speed. Too fast and you risk missing all of the strokes; too long and you risk washing out the lightning. My target shutter speed is usually 1/8 second, +/- 1/8 second—long enough to include multiple pulses, but not so long that I risk washing out the lightning.
When the sky is relatively bright, dropping to 1/20 second can help the lightning stand out better than 1/8 second, but risks losing secondary strikes. Conversely, when the sky is extremely dark and the lightning is firing like crazy, extending to 1/4 second might increase your chances for capturing multiple pulses.
Even with a polarizer on, getting the shutter speed to my sweet spot usually requires dropping to ISO 50 and stopping down to f/16 or smaller. In these situations, a neutral density filter is a big help, but take care not to let the shutter speed go longer than necessary.
Lightning is most likely to strike in or near the gray curtains that hang beneath dark clouds (clearly recognizable as distant rain)—not only near the center, but often on the fringe or just outside. And the darkest and tallest clouds are usually the most likely to fire lightning. If you’re in the storm that you’re photographing, you’re too close.
The best lens for lightning is usually a midrange zoom, such as a 24-70 or 24-105. If you find yourself reaching for your 16-35 (or wider), you’re too close.
I generally start fairly wide to increase my margin for error (to avoid missing a bolt just outside my frame), but once I’m sure I’ve captured some good strikes, I often tighten my composition. While this narrower field of view can reduce the number of frames with lightning, the ones I get are much larger in the frame.
Here are a few more composition points to consider:
There’s a lot of standing around while photographing lightning, but storms move, so the more you can keep your eyes on the sky (instead of your phone), the better you’ll be at keeping lightning in your frame as the storm moves, and knowing when the activity is picking up or winding down. The light can change by several stops as the storm moves, intensifies, or winds down, so check your exposure frequently. And monitor your surroundings for active cells moving up behind you.
Be aware that electrical storms can move quite quickly, and more than one cell can be active in a given area, so monitor the sky closely—not just the storm you’re photographing, but scan for potential cells that could be sneaking up on you. Sometimes this simply means adjusting your composition to account for shifting lightning; other times it means retreating to the car if the cell threatens your location. No shot is worth your life.
One final note: If you check my exposure settings, you’ll see that my shutter speed here was .4 seconds, well outside the 1/20-1/4 second range I suggest. But if you look at the other settings, you’ll see that I’d opened up to f/7.1, and had cranked my ISO to 400, an indication that twilight was settling in. Successful lightning photograph is all about contrast, and the darker the sky, the better the bolt stands out, even in a longer exposure. Had we stayed past dark (and lived), we could have jettisoned the Lighting Triggers and used multi-second exposures.

For many years my website has featured my workshops, while my social media pages (WordPress blog, Instagram, and Facebook) have been where I’ve shared my latest photography. While I originally kept galleries on my Eloquent Images website, I rarely updated them and after a while the website galleries ceased being a reliable reflection of my current work.
About three years ago I redesigned my website, completely changing the interface and removed the galleries entirely, doubling-down on my blog galleries. But when I started hearing from people that they couldn’t find my latest images online, I realized that, even though they’re really easy to find in the galleries right here on my blog, many people don’t take the trouble to look for them—if they don’t see a Galleries option on the website, they just move on. I made a mental note that I need to bring my website galleries back, but between workshops and travel, I never found the time.
Well guess what—suddenly I have time! So a few weeks ago I asked my webmaster to add galleries to my website, and I’ve spent the last couple of weeks populating them, and having far more fun than I could have imagined. My webmaster labeled my six galleries Gallery 1, Gallery 2, …, Gallery 6. Hmmm, surely I can do better than that. I thought long and hard about more descriptive names, trying on locations and other similarly prosaic labels, before deciding I need themes to describe my motivations for clicking my shutter.
You may or may not know that when I decided to make photography my profession, I promised myself that I’d only photograph what I want to photograph, that I would never take a picture just because I thought it would earn me money. I’d just seen too many miserable photographers earning a living but hating what they do. But since all I want to photograph is nature (which, while universally loved, is not universally purchased), I needed to come up with a way to earn money. I landed on photo workshops, which perfectly leveraged my prior career in technical communications (tech writing, training, and support) and my love for both photography and nature. Not only did this enable me to photograph only what I love, my images turned out to be the perfect intro and marketing tools for my workshops: if you like my images, you’ll probably like my workshops; if you don’t like my images, you probably won’t be happy with my workshops. (Of course I do sell images too, but image sales isn’t an essential part of my business and never motivates me to take a picture.)
So I guess it should have been no surprise that thinking about what my gallery themes should be would lead me down this rabbit hole of introspection. Many photographers create spectacular images that reveal the damage humans are doing to our natural world, but I seem to simply be driven to share nature’s beauty, both the obvious and the overlooked. Rather than a conscious choice, this is more an organic outcome of a life spent seeking and finding happiness in the natural world, combined with regular old human nature that causes most of us to find pleasure sharing the things we love most: “Here’s something that makes me happy—I hope it makes you happy too.” Here’s where the rabbit hole led me—I can’t think of a clearer distillation of the things in nature that move me:
These galleries are a work in progress. Assembling them, I quickly realized that many of my images would work in more than one gallery, but I decided not to duplicate any image. Rather than a comprehensive retrospective, my new galleries are more of a summary of my own favorites. But I’m still adding to them, so feel free to suggest additions you think I’ve overlooked. Or simply browse and enjoy.

Photographing lightning is about 95 percent arms folded, toe-tapping, just-plain-standing-around-scanning-the-horizon—interspersed with random bursts of pandemonium. Usually, after all that waiting waiting around, with the first bolt usually comes the realization that you anticipated wrong and either, 1) the lightning is way over there; or 2) the lightning is right here (!). What generally ensues is a Keystone Cops frenzy of camera bag flinging, tire screeching, gear tossing, tripod expanding, camera cursing, Lightning Trigger fumbling, bedlam. Followed by more waiting. And waiting. And waiting….
I’ve always thought that the waiting part of lightning photography is a lot like fishing (spiced up by the understanding that these fish have the ability to strike you dead without warning). Both are an intoxicating mix of serene communing with nature and an electric current of anticipation. And whether you’re fishing for trying to photograph lightning, the strike far from a guarantee that you’ll reel anything in. Just as fish somehow slip the hook, you a lightning strike can come and go before even the fastest cameras can respond. Most of my lightning “the one that got away” stories turn out to be something I’ve done wrong (and my list of stupid mistakes is too long, and embarrassing, to detail here).
One frustration that I’ve learned to deal with is that when a Lightning Trigger is attached and turned on, the camera is in pre-focus mode (to allow the fastest shutter-lag), which disables LCD review—and I guarantee that the surest way to ensure another lightning strike is to turn off your Lightning Trigger because the second you turn off your Lightning Trigger to see if you got that last strike, a spectacular triple-strike will fire right in the middle of your frame. Guaranteed. (This is an extension of the axiom every photographer knows: The best way to make something you’ve been waiting for happen, is to put away your camera gear.) Though there’s no way to know, I would bet that each time you pull the line out of the water to make sure the worm is still there, the “big one” you’ve been dreaming about swims right by.

About this image
Still reeling from Saturday’s 12-hour drive to the Grand Canyon for our 2015 Grand Canyon Monsoon photo workshop, and with clear skies in the forecast for Sunday, Don Smith and I planned to take the day to recharge for the workshop that started Monday. But dark clouds after lunch sent us racing up to the rim (a 15 minute drive) to see what was going on (see Keystone Cops reference above).
Starting at Grand View Point, we quickly set up our tripods, attached our Lightning Triggers to our cameras, and aimed toward promising clouds in the east, up the canyon, and waited. Soon these distant clouds weakened, but a new batch of clouds overhead darkened, and a breeze picked up—usually a sign that rain is coming. Aside from the spectacular beauty, another great thing about photographing lightning at the Grand Canyon is the expansive vistas that allow you to photograph distant lightning. Basically, we want to be photographing someone else’s storm—if you’re in the storm you’re photographing, you’re too close. So when the rain started falling we packed up and bid a hasty retreat; by the time we made it to the car, the rain had turned to hail we could hear thunder. Since the storm appeared to be moving west, we drove east to get on the back side of it, eventually ending up at Lipan Point—one of my favorite spots for lightning because it has long views both up and down the canyon.
We set up west of the Lipan vista, enjoying relative peace and quiet away from the summer tourist swarm. The cell that had chased us from Grand View was diminishing, but we could see an even more impressive cell moving up to replace it from the south. The first bolts this storm fired were above the flat, scrub pine plain south of the rim, but it was moving toward the canyon so we set up and waited. At first I hedged my bets, composing wide enough to get lightning over the less aesthetically pleasing terrain, along with the canyon. But as the cell moved out over the canyon, my composition moved with it.
When photographing lightning, not only do you need to get the light right, you need to make sure your shutter speed is slow enough to capture secondary and tertiary strikes, but fast enough that the lightning doesn’t get lost in the background. That’s because a long shutter speed, even if the rest of the scene is perfectly exposed, will wash out the lightning (not problem at night, when there’s plenty of contrast). The light this afternoon was particularly schizophrenic, so because I prefer photographing lightning in manual metering mode (I explain in the lightning tutorial linked above), I had to frequently monitor the changes and adjust my exposure accordingly.
That afternoon we enjoyed about a half hour of quality shooting before lightning moved too close for comfort. In that span I saw at least a half dozen canyon strikes, not an especially active storm by Grand Canyon standards, but one that delivered several photogenic strikes like this one (my favorite of the bunch). Lightning photography can be mesmerizing, and when the strikes just keep getting more and more spectacular, it’s easy to lose track of (or not care) how close the storm is. Fortunate for us this afternoon, a second active cell snuck up behind us and jarred us from our trance. It was over less photogenic terrain, so we managed to pull ourselves away before things became too dangerous.

We’ve reached that time of year where everyone is compiling their Top 10 lists. I like retrospectives as much as the next person, but I’ve always resisted assembling these “top-whatever” end-of-year countdowns of my own images. Then last week Sony asked me to provide my favorite image of 2019 and I struggled mightily because it felt like they were asking me to pick a favorite child—which, as we all know, can vary on a daily basis. (Just kidding—I love you girls!) But seriously, I did hesitate because I wasn’t sure Sony and I aren’t defining “favorite” the same, and in fact favorite for me can mean many things that are easily skewed by mood and memory.
So instead of attempting to rate and rank my images at year’s end, I prefer using them as a catalyst for reflection. Each December I go through the images I’ve processed from the waning year and reflect on the circumstances of their capture. Rather than focus on individual images, I’ll start by reflecting more on the experience surrounding three memorable shoots that stand out from in a year filled with too many individual highlights to detail here (but feel free to go through my 2019 blog posts). And if you’re just here for the pictures, jump to the bottom to see a gallery of 2019 images that make me happy (including some new images that I’ve never shared).
I can think of no better way to start a year than the opportunity to photograph something I’ve fantasized about seeing for my entire life. When Don Smith and I traveled to Iceland last January, I had two goals in mind: scout for our upcoming photo workshop, and see the northern lights. The scouting trip was a great success, but with just a couple of days to go, and not for lack of trying, we still hadn’t seen the northern lights.
On our penultimate night we finally witnessed a nice aurora display that spread ebbing and flowing veils of green, coloring the sky above Glacier Lagoon from the horizon to about 45 degrees—I was thrilled and felt like my aurora dreams had been fulfilled. Then came our final night, when I learned what a real northern lights display is.
There really are no words to describe this experience, so I’ll just let my images speak for me. I will say that two-dimensional, still images don’t fully convey the experience of witnessing the aurora in person, but they do at least least give you an idea of the drama and magnitude: for one thing, the foreground was darker than what I captured (though it was bright enough that I walked around without a flashlight); the aurora moves, maybe at about the speed of the minute hand on a clock. And while the previous night’s display was only in the northwest and covered no more than a quarter of the sky, the display this night at times spread across the entire sky and needed to constantly spin around to make sure I wasn’t missing something.

Don and I did two winter photo workshops on New Zealand’s South Island in 2019. The first was our regularly scheduled New Zealand winter workshop, the second was a workshop we put together to guide a group from the Sony Alpha Imaging Collective. Though night photography was a priority for both groups, the moon and clouds hindered the first group’s efforts (until our final night, but that’s another story).
The second group fared better in the night photography department in general, one day in particular stood out. We started with a 3 a.m. starlight shoot at Lake Wanaka, then made the 3-hour drive to Aoraki National Park, where we spent a day photographing spectacular fog and hoarfrost along the way, and glaciers, lakes, and mountains once we arrived. Following our beautiful sunset on the shore of Tasman Lake, we bundled up to wait for dark and were rewarded with one of the most breathtaking Milky Way shoots in my life (which has been filled with many Milky Way shoots).
All I could think about on the foggy 3-hour drive back from Aoraki was curling up in my warm bed and getting some much needed sleep. But when we pulled into our hotel a little before midnight and I looked up and saw stars, it felt like someone had flipped the switch on my reserve generator and I just had to go back out and shoot some more. So while everyone else headed to their rooms to process images or sleep, I grabbed my camera gear and raced to the lake. For the entire 10-minute walk to Wanaka’s iconic willow tree, I kept an eye on a bank of fog massing on the far shore and willed it to hold off long to allow me a few frames.
Finding the view of the tree completely devoid of people (a personal first), I photographed for nearly an hour in glorious solitude. While waiting for each exposure to complete, and with nothing in my world but me, my camera, and a sky full of stars, I reflected on the last 21 hours realize this was the perfect cap to what was no doubt one of the most memorable photography days of my life.

Each year starting in 2013, Don and I have guided two photo workshop groups around both rims of the Grand Canyon, chasing the lightning, towering clouds, and dramatic light of the Southwest’s summer monsoon. This year’s Grand Canyon monsoon trip was filled with lots of great memories and photography that included rainbows and more lightning strikes than I can count, but one experience in particular stands out above the rest.
The best vantage point for an electrical storm on the Grand Canyon North Rim is probably the twin view decks at Grand Canyon Lodge. Not only do these open-air decks provide a beautiful, sweeping view of the canyon, they’re shielded from lightning by a network of lightning rods, and anchored by an enclosed viewing area for retreat when the action gets too close.
We’d been watching a storm build in the distant west, but unlike most storms here, this one moved toward us and didn’t veer or fade as it approached. The storm arrived so quickly, and so mesmerized were we by its power, that it was almost on top of us before we could react. The rain was just starting to pelt us when Oza Butte, about a mile away, was stabbed with multiple strokes that made everyone jump and gasp. That was our signal to grab our gear and race for cover.
Safe inside as the storm raged around us, everyone in the group buzzed about “the big one.” I moved around the room and confirmed that nearly everyone had some version of this spectacular strike, then scrolled through my own frames holding my breath until I came across this one. Many in the group only had the bolt on the right because that’s the direction the lighting had been firing. I was silently patted myself on the back for having the foresight (good luck) to have widened and shifted my composition to the left shortly before this bolt hit. First, because it seemed like the storm was moving in that direction, and also because I wanted my composition to include more canyon.

Every August for the last seven years, good friend and fellow pro photographer Don Smith and I have done a Grand Canyon Monsoon photo workshop where we attempt to, among many other things, photograph lightning. I say “many other things” because Grand Canyon doesn’t need lightning to be spectacular. And even without lightning, the monsoon storms that build above the canyon most afternoons add beautiful clouds, rainbows, and sunsets to the magnificent vistas. (We also try to include a Milky Way shoot.) But as nice as all that other stuff is, most people come for the lightning. Don and I do our best to establish realistic expectations, because as reliable as the summer monsoon is in the American Southwest, nothing weather related is a sure thing.
This year I got a reminder of that fact by watching the weather forecasts leading up to our workshops. Each year in the weeks before first workshop’s start date, I regularly (obsessively) monitor the Grand Canyon weather forecast. This is a futile exercise that does nothing but add stress because no matter what the forecast is, I get anxious. No lightning? Oh no! This year’s monsoon is a dud (a “nonsoon”). Lots of lightning? Oh no! All the good stuff will be over before we get there. Sigh.
Coming into this year’s workshops, Don and I had done 12 (two per year for six years). For the first few years, I’d estimate that in about half, everyone in the group captured multiple lightning strikes (in some groups the number of successes approached or exceeded 100). In many of the less successful workshop, a few people got lighting and a few didn’t. And a few were a complete shutout. But the last two years had been great, with everyone in both groups getting multiple strikes.
Part of this recent success I attribute to just plain good luck, and part I attribute to experience—Don and I have gotten better at preparing the groups, teaching lightning photography, troubleshooting Lightning Trigger and camera problems, reading and responding to the conditions, and simply knowing where to be and when to be there.
This year’s first workshop would start on July 31, but as July wound down, each day’s forecast called for blue sky. Blank. Blue. Sky. Maybe our run of good luck was about to end. Fire up the anxiety engines. Compounding my stress was the realization that this would be our 13th monsoon workshop. And we had 13 participants—I’m not a particularly superstitious person, but still…. (We normally cap our groups at 12, but a small administrative hiccup resulted in an extra enrollee.)
But, to make a long story just a little shorter, we needn’t have worried. On the day our first workshop started, Mother Nature flipped the lightning switch and by the end of the third day (of five), everyone in Group 1 had their lightning. Phew. As it turned out, that group ended up with multiple lightning opportunities. Halfway there….
The second group had to wait until the fourth day, and only got one good shot at it, but theirs was one of the most spectacular lightning storms I’ve ever witnessed (Lightning Explosion, Oza Butte)—both for its intensity and its proximity.
Don and I usually use the day between workshops to “recharge” (pun unavoidable), but at dinner that evening we’d been monitoring our (fantastic) lightning app, My Lightning Tracker Pro, we saw that lightning was firing nearby and just couldn’t resist going out on our own.
Picking the lowest hanging fruit, we ended up at easily accessible Mather Point. The show was well underway when we arrived, but didn’t need to wait long before our Lightning Triggers started firing. I captured a dozen or so frames with lightning that evening, some with multiple bolts, but the unique, circuitous path followed by one I share above was my favorite.
I recently rewrote the lightning explanation portion of my Lightning Photo Tips article. As you’ll read below, lightning always follows the easiest path to resolve its polarity discrepancy, so I wonder what atmospheric machinations caused this serpentine bolt.
A lightning bolt is the atmospheric manifestation of the truism that opposites attract. In nature, we get a spark when two oppositely charged objects come in close proximity. For example, when you get shocked touching a doorknob, on a very small scale, you’ve been struck by lightning.
The primary process at work in an electrical storm is convection, the circular, up/down flow that happens when heat is applied to a fluid. As air warms, it becomes less dense and rises. The rising air cools with altitude and becomes more dense, causing it to sink. But the sinking air warms as it loses altitude, eventually rising again, and the cycle continues…. (Convection is also the process behind the bubbling of boiling water.)
Convection’s up/down flow creates turbulence knocks together airborne molecules, striping their (negatively charged) electrons. Lighter, positively charged molecules are carried upward in the convection’s updrafts, while the heavier negatively charged molecules remain near the bottom of the cloud. Soon the cloud is electrically polarized, more positively charged at the top than it is at the base.
Extreme polarity can also happen when a negatively charged cloud base hovers above the positively charged ground. Either way, nature resist this charge disparity and tries to resolve it as fast as possible: a lightning bolt.
Nature always finds the easiest path. If the easiest path to electrical equilibrium is between the cloud top and bottom, we get intracloud lightning; if it’s between two different clouds, we get intercloud lightning. A cloud-to-ground strike occurs when the easiest path to equilibrium is between the cloud and ground.
With lightning comes thunder, the sound of air expanding explosively when heated by a 50,000 degree jolt of electricity. The visual component of the lightning bolt that caused the thunder travels at the speed of light, over 186,000 miles per second (from the human perspective, that’s virtually instantaneous, regardless of your distance on Earth). But lightning’s aural component, thunder, only travels at the speed of sound, a little more than 750 miles per hour—a million times slower than light.
Knowing that the thunder occurred at the same time as the lightning flash, and the speed both travel, we can estimate distance of the lightning strike. At 750 miles per hour, thunder will travel about a mile in about five seconds: Dividing the number of seconds between the lightning’s flash and the thunder’s crash by five gives you the lightning’s distance in miles; divide the interval by three for the distance in kilometers. If five seconds pass between the lightning and the thunder, the lightning struck about one mile away; fifteen seconds elapsed means it’s about three miles away.
One of the things I love most about photographing lightning at Grand Canyon is the ability to do it in relative safety. With a few notable exceptions (see Lightning Explosion above), most of the lightning we photograph is at least 10 miles away, distant enough that we rarely hear thunder. I won’t pretend that any lightning photography is completely safe because the safest place to be in an electrical storm is always inside. But standing on one Grand Canyon rim while waiting for lightning to fire on the other rim, as we did this evening, feels more like magic than madness.

I don’t usually write a brand new blog in the middle of a workshop, but I have to share last night’s experience
August 7, 2019
Scanning the southern horizon from the view deck of Grand Canyon Lodge on the North Rim, I saw no sign of lightning. Far to the south was a somewhat promising curtain of rain, maybe 30 miles beyond the South Rim. With nothing to do until I met the group for our sunset departure, I found a composition I liked and pointed my camera (with Lightning Trigger engaged) in that direction.
Soon others joined me—with my lightning app showing activity 50 miles distant in the general direction my camera pointed, I made the call to bag the sunset shoot and put all our eggs in the lightning basket. (A decision I might not have made had this second workshop group already had the lightning success the first had). Turns out that was a good call.
About an hour later, when lightning started firing to the west, I stubbornly stuck with my composition, but instructed the rest of the group to point their cameras toward the more sure thing. My reasoning was that since I had over 100 lightning strikes from the first workshop, I could afford to be selective and take a chance on the composition I preferred, but everyone who hadn’t had a success should play the odds.
My storm completely fizzled, but the storm cell to the west was very active and appeared to be moving closer. I finally admitted defeat and gave up on my cell, turning my attention to the active cell just about the time we started hearing thunder. Within minutes the storm was on top of us and suddenly we couldn’t tell which thunder went with which bolt.
Huddled in relative safety beneath the lodge’s lightning rods, the next 20 minutes provided the most jaw-dropping electrical this California boy has ever seen—maybe all lightning storms are this spectacular, but I’ve never been that close. We gave everyone the option of retreating to the lodge’s enclosed viewing deck, but everyone steadfastly stuck to their tripods. The lightning was firing two or three times per minute, each strike so close that we couldn’t couldn’t fit the entire bolt in our frame. Then the wind kicked up and soon thereafter the sky opened, so we grabbed our cameras and headed inside.
As the lightning flashed in the pictures windows, we reviewed our captures on our LCDs and shared our bounty with each other. Everyone had multiple lightning captures, and it seemed like virtually all in the group had some version of this bolt striking Oza Butte, about one mile away. It was interesting to compare the differences between each person’s capture—not only did they vary with the composition, they also varied with the exposure time (more or fewer strokes and filaments) and camera type (some cameras trigger their shutters faster than others).
This image is a perfect example of what I love about still photography: It freezes an instant in time that is already memory by the time my brain registers it, allowing me to spend as much time as I want scrutinizing detail I’d never see otherwise. I can’t tell you how long I’ve studied this image already, and I’m still find new things.
Posted on August 5, 2019
In a day of surprises, I think the most surprising thing was finding myself completely alone on the South Rim of the Grand Canyon—in the middle of a workshop. The sun had set, the tourists had gone to dinner, and the rest of my group, thanks to an unexpected turn of events (stay tuned), was with my workshop partner Don Smith at Desert View, about ten miles east. I love leading workshops, but the opportunity to enjoy a summer sunset alone at the Grand Canyon was too rare to not to appreciate. And as if that wasn’t enough, I was being treated to one of the most spectacular lightning displays I’d seen in all my years of photographing the Grand Canyon monsoon.
The weather gods had been messing with us since the workshop’s start two days earlier. The forecast for our first two days was so good, Don and I had virtually guaranteed everyone a lightning bolt (or ten, or 20, or…) on their memory cards by the time we headed to the South Rim on Day 3. But on Day 1 we got too much rain and not enough lightning (not unprecedented), a loss largely assuaged by a gorgeous rainbow at sunset (phew). No worries, the Day 2 lightning forecast was even more promising.
While we did see a bolt or two on the second day, we got nothing close to the classic lightning displays the North Rim frequently serves up during the Grand Canyon Monsoon. Even without any lightning photos, the day was salvaged by the night’s fantastic Milky Way shoot at Cape Royal—an evening so warm that most of us kept the jackets packed and did the whole thing in T-shirts.
But lighting is this workshop’s Holy Grail, and the pressure was building for Don and me. For a few reasons, the North Rim is usually generates about 80 percent of our lightning success. But after being shut out for our two North Rim days, now it was time to motor to the much more crowded South Rim, where the crowds are oppressive and weather forecast called for a measly 10 percent chance of thunderstorms. Suddenly my optimism was waning.
Mother Nature is fickle, and I’m pretty sure she was punishing me for being a little too cocky at the beginning of the workshop. Because on the road to the South Rim (about the time I started to admit serious doubts about our lightning chances), she started filling my windshield with billowing cumulus clouds—not friendly cotton-ball puffs, these clouds were dark, angry towers. By the time we checked into our hotel, our lightning app was showing signs of sneaking activity sneaking up from the south (behind us).
Though nothing was happening near the canyon yet, experience has taught us to be proactive when the storms are building. So rather than wait until the planned sunset departure time, Don and I herded the group to the cars and we bolted for the rim as soon as we could get everyone assembled. Turning east on Desert View Road toward our sunset destination, Desert View, we pulled over at the very first vista. We hopped out to take a look and as Don and I surveyed the view, someone spotted lightning directly across the canyon. Showtime.
This was indeed a great show, with at least one or two bolts per minute for nearly an hour. Within 15 minutes it was pretty clear that everyone had captured multiple strikes and Don and I could relax—everyone would go home with the lightning photos they came for. The storm was still active when increasing wind and threatening clouds led us to decide it would be prudent to move on.
The next stop on the way to our way to Desert View was Grandview Point, and that’s where things took an unexpected turn. First, when I went to change the precariously low battery on my Sony a7RIII, I realized my backup battery was at home on the charger (gone are my Sony a7RII days when I carried six batteries). But that crisis was soon set aside when one of the members of the group had an emergency that required her to return to the hotel. After a bit of discussion and a little math (Do we have enough seats for the rest of the group to continue to Desert View for sunset? Answer: Yes, with none to spare), I drove her back while everyone else continued on to photograph sunset.
Back at the hotel I did a bit more math and realized there was no way I could make it all the way out to Desert View in the 50 minutes remaining until sunset. But seized by FOMO*, I grabbed my a7RII, checked the battery (fully charged—yay!), and headed back to the rim with no particular plan—even if I couldn’t make it back to the group, I just wanted to be somewhere for sunset. At the junction with Desert View Road I headed east again, away from the Grand Canyon Village congestion and toward some of the less crowded vistas.
The entire sky was gray and at first I thought sunset might be a dud, but then I caught a thin layer of brightness in my rearview mirror and realized there was a hole on the horizon—when the sun drops into it, everything might just light up for a few minutes. I checked my watch and goosed the accelerator hoping to make it as far as Grandview Point. Unfortunately, in the national parks you can only go as fast as the next Winnebago, and sunset was less than 10 minutes away when I dove into my Grandview parking space. I grabbed my camera bag and dashed down the trail to my favorite view atop an exposed rock outcrop, not realizing until headed off-trail that I was still in my flip-flops. But with no time to go back for more sane footwear, I continued slip-sliding my way down to my destination and (barely) made it with all limbs intact.
The color was starting but as soon as my camera was set up, but I took a few seconds to get my adrenalin under control. The first thing that struck me was the quiet, most unusual for a Grand Canyon summer sunset. I attributed it to the storm, which had just moved on from here, and the fact that Grandview isn’t heralded as a sunset location (because most non-photographers like their sunset views to face west, and there are better spots at Grand Canyon for that).
As expected, there was indeed great color that evening, but even more exciting was all the lightning in the east: Cloud to ground, cloud to cloud, cloud flashes, multiple bolts, extreme zig-zags—pretty much a who’s who of lightning, several times per minute. Most of the lightning was firing somewhere in the empty desert beyond Desert View, but it looked far enough away that the group was safe. From my perspective there was no canyon or anything else interesting in the direction of extreme activity, so I pointed my camera at a somewhat promising curtain of rain that aligned better with my view of the canyon—and hoped.
Photographing lightning is more thrilling than I can describe, and I can think of no better place for it than Grand Canyon. The distance of the views here relieves (most of) the anxiety that comes with viewing lightning—so far on this trip I’ve captured 116 frames with lightning (yes, I count them) and still haven’t been close enough to any of them to have heard their thunder. And Grand Canyon puts the actual lightning experience on steroids because during the long peaceful periods between strikes you’re gazing upon one of the most breathtaking views on Earth. When a bolt explodes from the clouds, its metaphorical jolt to my psyche seems to match it’s actual 50,000 (ish) volt electrostatic jolt.
I only captured a half-dozen or so strikes over the canyon that evening, but all I need is one. This one touched down several minutes after sunset, about 30 miles away. It came right at the peak of the color and couldn’t have been more perfectly timed or placed. And as I waited for the next bolt to trigger my camera, I got to enjoy this view the same, infinitely more spectacular, light show the rest of the group was enjoying—in glorious, absolute quiet.
