Scorched leaf detail, Arnhemland. Canon EOS 5DSR, 100mm macro lens, 1/160 second @ f4, ISO 400, tripod. Click the YouTube link below to see a mini-slide show.
In many parts of Australia, fire is part of the seasonal ebb and flow. Flying into Arnhemland last year, we could see lots of spot fires all around. My understanding is some are lit by lightning stikes, others are intentionally lit for land management. Whatever the reasons, they add an accent to the landscape.
What struck me most about the aftermath was the colour. Rich orange and red browns dominated small sections of the bush and so the challenge was to create an interesting composition. However, as you will see from the location shot (you'll see it on the website), it was a very busy area with strong overhead light. It was challenging!
My solution was to get in close using a macro lens. I also looked for areas where the leaves were backlit by the sun, but the background was in the shadow of a hill or outcrop, thus making a dark background against which the leaf would stand out.
For macro work, I like to work on a tripod so I can precisely control my focus. The closer you focus, the less the depth-of-field, the less of your image will be in tack sharp focus. However, I didn't want the entire leaf to be sharp, just a section of it.
So with the camera nice and steady on a tripod, what's the problem? There was a very slight breeze. It really was hardly a hint of moving air, but it was enough to move the leaves ever so slightly. To maintain my aperture, I needed to choose a higher ISO setting (400 in this case) to keep my shutter speeds fast enough to arrest any movement.
