I’ve been photographing Kilauea’s eruptions, in many forms, for 15 years, but never anything close to the spectacular display my workshop group and I witnessed in September. It wouldn’t be hyperbole to say that this was one of the most memorable experiences of my life. (I’ve said that about Kilauea eruptions before, but each time I say it, Kilauea seems to say, “Oh yeah? Hold my Mai Tai.”)

As a photographer who obsesses about controlling every pixel in my frame, and who (semi-) jokingly asserts that I don’t photograph anything that moves, there was a lot going on atop Kilauea this morning. Anybody up there with a camera could have snapped a few frames and captured something worthy of sharing, but whether it’s a vivid sunset, dancing aurora, or fountaining lava, serious photographers need to separate themselves from the “anybodys” and pay attention to the little things easily overlooked in the thrill of the moment. This morning on Kilauea, with an obvious focal point and empty foreground, the biggest (and most easily overlooked) challenge was the constant motion in the scene.

Let’s review: Photography is the futile attempt to convey a dynamic world using a static medium. Though that’s literally impossible, what is possible is conveying the illusion of motion—that is, capturing the scene in a way that enables viewers to infer its motion. Finding the shutter speed that freezes a moving subject in place or renders it with some degree of motion blur, while getting the light perfect, is a basic photography skill that simply requires mastery of the three exposure variables.

Motion in a landscape image can take many forms, some easier to address than others. Though waterfalls and whitewater rapids may move fast, at least they stay in one place while the water moves within. But other natural subjects move more unpredictably. Lightning, for example, comes and goes so suddenly, I never even consider using my own reflex/reaction skills to freeze its transient existence—I simply connect my Lightning Trigger, aim my camera, and wait for my trigger and camera to do the work. Ocean waves, while less organized than whitewater, are at least predictable enough to anticipate and time—that said, I generally prefer to simply shoot a series of wave images with varied timing and motion effects, then pick my favorite later.

Somewhere between lightning and waves on the predictable/random continuum are atmospheric phenomena like the northern lights, and regular old clouds. Though they’re in constant (seemingly) random motion, that motion is usually more my speed—slow enough to anticipate and adjust my composition and exposure without feeling too rushed.

But it’s not just about how you render the motion—another complicating factor is paying attention to subjects that don’t stay put: a composition that was perfect seconds ago could be completely out of whack right now. Which happens to be the biggest challenge this memorable morning in Hawaii.

Now might be a good time to mention that part of my desire to control my entire frame makes me especially obsessive about both the borders of my images, as well as the relationships of the elements in my frame that draw the eye. That means trying to avoid cutting strong elements on the edges of my frame, creating a sense of connection and balance between strong visual elements, and avoiding (or minimizing) visual elements that compete with my subject or subjects. So when my subjects are in motion, as they were on Kilauea this morning, I need to monitor and adjust continuously.

Arriving with my workshop group several hours before sunrise, the total darkness meant I only had to contend with 800-foot explosive lava fountains and the lava rivers surrounded by a sea of black. The lava fountains, while exploding violently and pretty much non-stop, were far enough away that they seemed to be moving in slow motion. The lava rivers, though constantly ebbing, flowing, and changing course, moved slowly enough to be relatively manageable too.

My goal was to freeze the lava’s motion in place, and soon I settled on a shutter speed I was confident would do that even at my longest focal length. With the unchanging light (dark) and a shutter speed I knew was fine, it wasn’t long before I found a rhythm, complementing compositions centered on the “stationary” lava fountain (the lava was moving, but the fountain stayed in one place) with the current position of the flowing lava rivers, then timing my shutter click for when the latest fountain peaked or spread most dramatically. I worked this way for a couple of hours, mostly using my 100-400 and 1.4X teleconverter, zooming in and out and switching between horizontal and vertical compositions.

Things changed when sunrise started painting the sky pink and revealing a previously unseen plume of billowing smoke, vapor, and tephra. Suddenly, my priorities switched to wide angle to capture all the additional beauty brought by the increasing light. And just as suddenly, I had to adjust the compositional imperatives underlying my prior rhythm, now factoring into the mix the wind-whipped smoky plume tower that expanded and shifted by the second, the pink clouds, and even new detail on the caldera floor. And with the rapidly brightening sky, an exposure that worked 30 seconds ago, now blew out the sunlit highlights. Not only that, I knew the plume’s gorgeous warm light was peaking and would only last for another minute or two, further ratcheting up my urgency.

Switching to my 16-35 lens, I framed up a completely new composition and adjusted to a new combination of motion considerations. In this case, including the lava and rising plume were no-brainers, but the goal should be more than simply taking a picture that includes both—everything needs to work together to create something that stands out from the thousands of other images captured at the caldera that morning.

Managing all of a scene’s moving parts is what good photographers are supposed to do. That said, I notice—both in my workshops and online—that many photographers seem so focused on their scene’s one or two most prominent features that they lose track of still important secondary and tertiary elements. And when one or more of those less essential elements is moving, for example waves or clouds, their new position is easily overlooked, leading to random and often less than ideal results.

In this case, while keeping an eye on the active lava as I’d done all morning, I suddenly also needed to keep track of an expanding smoke plume that was in constant motion, illuminated by ever-changing sunlight. While not especially difficult if you’re paying attention, this doesn’t just happen automatically (and I have the pictures to prove it).

Keeping my borders as clean as possible became a prime concern, so I kept a constant eye on the shifting smoke plume to avoid cutting it off. On the left and top I just needed to keep the plume off the borders of my frame; since the wind had stretched the smoke far beyond any reasonable frame on the right side, I also needed to find the best place to cut that side with the right border. And as with my rapidly changing exposure, a composition that worked one second might need to be completely adjusted the next.

I tried to go just wide enough on the right to include all of the main (and most dramatic!) vertical section of the sunlit plume, and on the right went just a little wider than that to include that one small splash light—any farther right would have shrunk my subjects while adding nothing more than a homogenous horizontal band of brownish-gray smoke.

The result of all these machinations is this wide vertical frame that includes the fountaining and flowing lava that was the star of the show that morning, plus all of the sunlit portion of the beautiful smoke plume. Accomplishing this was not rocket science, and I’m not pretending to be special for achieving it. But I do think photographers often fall down when they get so caught up in the majesty of the moment that they fail to take that one extra step to account for the scene’s motion, and the importance of those subtle changes from one frame to the next.
