For the full context of my experience with Kilauea eruptions in general, and the events leading up to the fountaining portion of this episode (33), check out my prior blog post: Kilauea Eruption Episode 33, Part 1: So You’re Telling Me There’s a Chance…
The euphoria of our (very) early Thursday morning Kilauea eruption shoot powered my workshop group through the day and into Thursday night. Since we hadn’t made it back to the hotel until 4:00 a.m., I pulled the plug on our sunrise shoot (with zero objections), and the group didn’t gather again until our 1:00 p.m. image review session. It turns out many were so excited by the eruption experience, they opted for downloading and processing over sleep, but the few eruption images we did see definitely turbocharged the eruption enthusiasm.
The discussion during the afternoon meeting centered around whether the fountaining we saw was Kilauea’s new normal, or whether there might be more to come. My inherent optimism went straight to the fact that the prior episode (episode 32, in early September) had delivered the second greatest volume of lava to the caldera floor of all the episodes —the most of 2025 so far. And the latest USGS report said that continuing inflation at the summit meant more was coming. Yay.
The pessimist in me, that annoying little voice that keeps reminding me of the times Mother Nature has thrown cold water on high hopes, kept reminding me of the signs that the reliable eruption sequence that started in December 2024 might be flagging: the fountain height of recent eruptions had decreased significantly from its 1000+ foot peak; the gap separating each fountaining phase was increasing; and most significantly (in my mind), live webcams focused on the eruption’s vents showed that the activity we’d photographed the prior night had completely died—only smoke was visible where we had once seen bubbling, flowing lava.
Shortly after the image review session, we departed for the workshop’s sunset shoot at my favorite beach on the Puna Coast. That evening’s spectacular sunset pushed the eruption buzz to the background, and in a way felt like a fitting wrap-up to a fantastic workshop. We did have one more sunrise shoot planned, but I think everyone felt like it would be anticlimactic following all we’d photographed in the workshop so far. In fact, with flights to catch and coming off a night with very little sleep, when I suggested that we stay in Hilo and stick to the sunrise plan even if the eruption resumed during the night, the agreement was unanimous—we’d already had a great volcano shoot that would be tough to beat. (We’d already been up to Kilauea twice, so I also suggested that anyone who changed their mind should feel free to go up on their own if the eruption started.)
That plan lasted until 3:30 a.m. One of the workshop participants (who had his office manager in Ohio, where midnight in Hawaii is 6 a.m., monitoring the Kilauea webcams and reporting any changes) messaged the group, “It’s fountaining!” I was sound asleep, but the messaging frenzy that followed quickly roused me enough to grab my phone and check the webcam. I instantly knew the sunrise plan was out the window and we were going back to Kilauea, sleep be damned. When he said fountaining, he meant FOUNTAINING!!!
This fountaining was on an entirely different scale from what we’d seen the prior night, or even from anything I’d ever seen—like someone had kicked a giant sprinkler head on the caldera floor. (I learned later that it was the highest fountaining since early July.) Almost all of the group was wide awake and on the road in 20 minutes.
Even though we arrived before 5:00 a.m., a little more than an hour after the fountaining began, the park was much more crowded than we’d seen the previous night. We found parking, but just barely, and I knew the way cars were streaming into the park the open spaces wouldn’t last long.
Because of the crowds, we’d implemented an “every car for itself plan,” each doing its own thing while staying in contact. My car started at Kilauea Overlook, but found the view, while very close, was partially obscured behind the caldera rim. So we quickly doubled back to the Wahinekapu Steaming Bluff (steam vents), for the best combination of direct view to the fountaining vents, and fast access. There we reconnected with most of the rest of the group.
The view to the fountaining vents from the Wahinekapu is about 2 miles—our other option was the closer vantage point at Keanakako’i Overlook, on the other side of the caldera (where I shot the 2023 eruption). This is about 1.25 miles from the fountains, but also required a 15 minute drive followed by a 1 mile walk, and I knew that even if we found parking there (far from a sure thing), it would probably be starting to get light by the time we got our eyes on the eruption. Plus, having shot the eruption from Wahinekapu already, I knew we’d be close enough that 400mm would be plenty long enough.
I’m so glad we took the path of least resistance and stayed at Wahinekapu. Even though my brother Jay (who was assisting me in this workshop) and I had a very small window to shoot before we needed to head back to Hilo to catch our flight home, the timing of the eruption and our arrival couldn’t have been better. We started with nearly an hour of complete darkness, allowing exposures that froze the fountains without blowing out the highlights (overexposing the lava) to create the virtually black background that I think makes the most dramatic lava images. Following the complete darkness, we photographed through the slow transition into a beautiful sunrise. Finally, as the day brightened, we enjoyed about a half hour of the eruption’s towering plume warmed by lava-light from below, and low sunlight from above. Absolutely spectacular.
When I first photographed lava in 2016, I was learning on the fly. At night, standard histogram rules don’t apply to lava because a properly exposed frame will be almost completely smashed agains the left side (with much cut off), and often, especially on wider shots, with just few small highlight blips on the far right. Basically, job-one is to make the lava as bright as possible without blowing it out. And job 1a is to do that using a shutter speed that freezes the lava’s motion (unless motion blur is your objective). And finally, you really should do this using the best (lowest) possible ISO.
The mistake people make for any kind of motion blur, and I’ve heard a lot of “best shutter speed for Kilauea’s lava fountains” advice, is to assume that there’s one ideal shutter speed for freezing the lava fountains. There isn’t. Just as with flowing water, the shutter speed that freezes a lava fountain is a function of several factors: the speed at which the lava is moving—the higher the fountain, the faster the lava will be moving when it reaches the ground, the distance to the fountain, and the focal length.
Back in 2016 I started with extremely high ISOs to maximize my shutter speed, but have gradually, through trial and error, dropped both my ISO and decreased my shutter speeds for my lava images. At night, since depth of field is usually no concern, for most of my long telephoto shots using my 100-400, I now just shoot wide open, at f/5.6 for that lens. My exposure trial and error process involves taking a shot at a certain focal length, verifying that the lava is close to maximum brightness without blowing out, then magnifying the image in my viewfinder (or LCD) to confirm that there’s no motion blur in the lava fountain (make sure you check the lowest lava blobs, as they’ll be moving fastest). If that works, I lower my ISO and increase my shutter speed further, until I find the threshold where blur is discernible. Then, for a just-to-be-safe cushion, I bump my ISO and shutter speed back up to just slightly more than the prior settings (that I thought froze the lava).
I had to do this for every significant change in focal length, but it wasn’t long before I became pretty comfortable with my settings. And by the time this Friday morning lava fountaining started—having done it in 2016, 2022, 2023, and earlier that week—I was feeling so comfortable with my exposure settings that it was no longer a distraction. In fact, I was varying my focal length so frequently and clicking so fast, to simplify the process I just kept my exposure settings in the range I knew would work all the way out to 400mm. I was fine with this because a very satisfactory ISO 400 gave me a shutter speed in the 1/100 to 1/200 second range that I knew worked.
So bottom line? In total darkness, standing 2 miles away, at 400mm I was perfectly comfortable with f/5.6, ISO 400, and 1/100. But I hope you can see that my exposure settings probably won’t work for you if you’re much closer than 2 miles, and might be overkill if you’re farther away. In other words, I strongly encourage anyone who wants to photograph fountaining lava to apply my process, not my settings. (And there are many people with far more experience photographing lava than I have, so feel free to defer to them if their results confirm that they know what they’re talking about.)
This experience, the final shoot of my 2025 Hawaii Big Island workshop, wasn’t just the grand finale for this workshop, it was the grand finale of 15 years of Hawaii workshops. As I pare down my workshop schedule and ease (slowly) toward retirement, I decided a few months ago that this would be my final Hawaii workshop. Not because I don’t enjoy it (I do!), or because it no longer fills (it does!), but simply because I had better reasons to keep other workshops. Just as my final Grand Canyon raft trip was gifted with a beautiful, albeit less dramatic, crescent moon for our final sunrise, I can’t imagine a better Hawaii memory to go out on.

Thanks for the information on settings. Sounds like a good one to end on.
I immediately looked at the live camera and the volcano was oozing—not really shooting up into the air—and then it stopped, but at least I got to see it doing this thing a little bit.
amazing captures
WOW!!!
Gary…Wish I knew you were there.
We were staying at Volcano Lodge that week and WOKE UP at 3 am to this exciting event. Wonderful Shots…but hard to transmit the ROAR and AWE of molten rock being thrust higher than THREE football fields!
Wow. I’m so happy for you Gary and also wish I were there. Amazing images!!
A stunning image and a well written blog. I could feel the excitement building while reading it. Congratulations on a spectacular workshop!
Thanks so much, Chuck. Absolutely spectacular workshop in so many ways—one of the best!
