Photographers Credit
When I am not drawing from life in a museum or a wildlife sanctuary I often use photo reference material. I like to use my own photography where I can but often will use outsourced photography, particularly with overseas wildlife for reference. Here are links to some photographers/agencies who are kind enough to grant me a license to use their images in part or in whole at an agreed rate.
