A few days earlier I had taken a head shot of a female wood duck and was looking for a similar head shot of a male. When I saw this male wood duck in the half light, I knew that my project would have to be put on hold. The light illuminated his body beautifully but his head was far too dark and the background too bright. I made some adjustments in Photoshop using Levels for contrast and Luminance Masks to darken the background and brighten the bird.
