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.

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…

Earlier this month Don Smith and I traveled to the Grand Canyon for our annual Grand Canyon Monsoon photo workshops. I enjoy every workshop, but as a true weather nerd, these monsoon workshops are particular highlights in my year, and in Northern California we just don’t get that much weather—that is, unless you consider homogenous blue (summer) or gray (winter) skies weather.
For this trip, I started monitoring the Grand Canyon forecast about a week before the first workshop (okay, maybe a little earlier than that), and ramped up my queries as the workshop approached. If hoping and handwringing could make lightning, I’d never have a bad day at the Grand Canyon, but after three days of fairly benign conditions, workshop group number one was still waiting for their lightning. Then, like a walk-off grand slam, on our final full day Mother Nature gifted us with a spectacular, two-hour lightning show. Phew. In fact, that afternoon we got an entire workshop worth of dramatic weather in about five very intense hours. The day’s highlights included lightning and two rainbows, and wrapped up a mammatus (google it) sunset at Cape Royal. All’s well that ends well.
Contrast group one’s eleventh hour salvation with workshop group two, which hit the ground running (quite literally) before we could even have an orientation. The second workshop was scheduled to start with a 1 p.m. orientation at Grand Canyon Lodge on the North Rim. As go most mornings in monsoon season, the day started quietly, but a little after noon lightning started up across the canyon and Don and I set up our tripods, cameras, and Lightning Triggers. With the designated gathering place in front of the lodge, but the viewing deck and lightning show in the back, Don and I took turns running up front and dragging folks down to our location. Those who had arrived with camera gear were put right to work, while the ones who had left their gear in their car or cabin and had to race back up the hill to fetch it.
By 1:15 we were seeing one or two strikes per minute, sometimes more, spread across a fairly broad area of the South Rim. Soon Don and I had a dozen photographers spread across two outside decks separated by an enclosed viewing room. Most of them had never used a Lightning Trigger, or even photographed lightning, so once we got everyone assembled, most of the next hour was spent running around setting up and testing Lightning Triggers, helping people achieve the right exposure, and suggesting compositions.
During that first hour our cameras, set up and primed for action, enthusiastically fired away unattended. When I’m with my camera during a storm, I’m constantly tweaking my composition, exposure, and Lightning Trigger sensitivity. Left to its own devices, my camera ended up with over 400 frames of the very same scene, most of which had no lightning (because the trigger was detecting lightning too faint to register). Fortunately, by the time everyone had settled into a comfort zone with their cameras and Lightning Triggers, not only was the lightning display still going strong, it had moved closer (but remained at a relatively safe distance) and was isolated to the most photogenic part of the view. Our second hour was pure joy, as each dramatic strike seemed designed to outdo the one that preceded it.
The image I share at the top of this post came when the storm was at its most intense, moving southwest to northeast across (right to left) the canyon, just a little east of our location. The brightest bolt you see is striking just below the South Rim, between Yaki and Shoshone Points, but ten miles away.
When all was said and done, I got about 50 strikes that afternoon, and everyone in the group got multiple strikes as well. We had another productive lightning day the next day, but this is the day I’ll remember.
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 a little more problematic. It’s usually over before you can react, so without a lightning sensor to recognize lightning and click your shutter, success is largely dumb luck (few people are quick enough see it and click).
Lightning Trigger: The best tool for the job
A lightning sensor attaches to your camera’s hot shoe and connects 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 many lightning sensors from which to choose, before I bought my first one I did lots of research. 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 a little less than $400 (including the cable), the Lightning Trigger is not the cheapest option, but after leading lightning-oriented workshops for five years, I can say with lots of confidence that lightning sensors are not generic products, and the internal technology matters a lot. The Lightning Trigger is the only one I’d use and recommend (I get no kickback for this).
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 connecting the Trigger will disable your LCD replay, which means you won’t be able to review your captures without disconnecting (a simple but sometimes inconvenient task). You also won’t be able to adjust your exposure with the Lightning Trigger operational.
The Lightning Trigger documentation promises at least a 20 mile range, and I’ve seen nothing that causes me to question that. It 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. 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 about 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. In general, the more violent the storm, the greater the likelihood of bolts of longer duration, multiple strokes that are easier to capture. And my success rate has increased significantly beyond 2/3 since switching from a Canon 5DIII to a Sony a7RII (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 some or 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, with my camera at ISO 50 and aperture at f/16 (and sometimes 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.
Lightning is fast, really, really fast, so the faster your camera clicks the shutter after getting the command, 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.” The less shutter lag you have, the better your results will be. The two most important shutter lag factors are:
In addition to a lightning sensor and fast camera, you’ll need:
Lightning is most likely to strike in or near the gray curtains (clearly recognizable as distant rain) that hang beneath dark clouds. In addition to visible rain curtains, the darkest and tallest clouds are usually the most likely to fire lightning. Here are a few more points to consider:
Be aware that electrical storms can move quite quickly, so you need to monitor them closely. 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.
