There are few images that captures the wilderness essence of Chugach State Park more than this photograph. I went down to this popular spot to get a reflection image of Polar Bear Peak. While I was setting up the tripod and beginning to compose, three moose appeared behind me. The two cows went to my left and the young bull walked to my right and into the water.
At first I was annoyed, he was ruining my shot! But then I realized he was going to walk right into my composition. I had to think quickly, he was walking and drinking at the same time so I knew I needed make some quick exposure adjustments in order to stop his motion.
I had the camera set at f11 and the shutter was at 1/15th of a second, too slow. I had two options, increase the ISO or open up the aperture. The camera I was using was a poor high ISO performer and noise could be an issue in the shadows, even at ISO 200 (which was what the camera was set at). So I decided to sacrifice depth of field for a cleaner image and opened up the aperture to f5.6, making the shutter 1/60th. Luckily, I had a two-stop graduated ND filter already on the camera, so that really helped keep the mountain and sky from being over exposed.
