We have these mysterious butterflies around here in Arizona right now. I don’t know if it is a seasonal thing or what, but one morning I had an urge to go out and shoot them (ha...). I got those vibrant colors by setting a custom white balance. Then I added a vignette to focus more on the butterfly, and not all the pretty flowers in the background.
Specs: 1/400 sec. f/7.1 ISO 100 200mm.
