Two rounds of thunderstorms rolled through our home in Byng, Oklahoma last night. The first one skirted us to the north, so from our point of view, we had an excellent view of the right flank of the storm. It was the first time in the last couple of years that all the factors came together for me to make good lightning photos: little or no rain at my site, a very electrically-active thunderstorm, a lack of obscuring rain on my side of the storm, and no danger of being struck by lightning.
So, if we see a thunderstorm like this and want to photograph it, what do we need, and how do we do it? We need…
- A camera with manual controls of shutter speed, aperture, ISO, and focus
- A sturdy tripod or other way to hold the camera rock-steady
- A lens that will fill the frame with what we want to shoot (I know that’s vague, but stay with me.)
- The patience of Job
Last night my wife and I saw and heard an approaching thunderstorm. At first I went out onto the back deck, but only made a few frames there and decided the storm, moving from my left to right looking north, was about to be hidden by the house, so I relocated to the front deck.
Using my Nikon D700, a 36x24mm sensor DLSR, I started with my 20mm, a very wide angle lens. Mounted on a tripod, I set the ISO at 400, my aperture at f/8, and my shutter speed at 20 seconds. My 20mm has a hard stop at infinity, which is where I set focus. (Don’t try to use autofocus – it will never bite on anything in the dark.)
At that point, the patience plays a big role. Unlike fireworks, traffic, or Christmas parades (all of which are photographing lights) thunderstorms are irregular and unpredictable, so by the time you get set up, it could be too late, or the timing could be just right. Last night was such a “just right” night.
Within five minutes I felt the storm had moved away from me sufficiently to warrant switching to a 50mm lens, and I felt I wanted a slightly darker product than I was seeing on the monitor, so I changed to f/11 at 30 seconds. The 50mm filled the frame with the densest part of the lightning, and I felt several images looked good.
