Anatomy of An Image, Week 1

I've decided to start a new series on the blog called Anatomy of an Image. I'll post it once a week, on Mondays. I hope to talk more in depth about my thought process as I take each picture. I can't promise it'll be interesting, but maybe it'll be informative.

The Basics
Focal Length: 53mm on a crop sensor, equivalent to about 85mm
ISO: 400
Shutter Speed: 1/320 of a second
Aperture: f/2.8

The Story
The California Academy of Sciences in San Francisco. This frog was in a huge terrarium and he was maybe an inch across. And he was just stuck up on the glass like a little suction cup. So I got as close as I could,, focused with my center focus point and recomposed so he was in the left third of the picture. Then I took a few shots to make sure he would really be in good focus. Fortunately for me there was good light.

Anything else I should be adding to this series? Other information you would like added? Or maybe this completely bores you. Whichever it is, let me know.
