About Phil Colla

I am a natural history photographer. I enjoy making compelling images in the ocean, on land, and in the air. I have maintained the Natural History Photography blog since 2005 and my searchable Natural History Photography Library since 1997. Here are some tear sheets and behind the scenes views. Thanks for looking!
