Collosus up in the Mammal Division. Most of those shots were taken on film, except for a few that I did on the 2mp camera. The one above is of the gorilla's hand, desaturated, duotoned, and saved as an RGB image. I'm hoping the shots on TRi-X come out anywhere near what I imagined.
This was a rather awesome experience. Being so close to a lowland gorilla, and being able to photograph him at will gave me a profound appreciation for their similarities and many differences from us.
