If MoMA was really looking to break ground in their New Photography series, they couldn't do much better than this amazing self-portrait taken by an un-named Indonesian macaque. I'm pretty sure he hasn't exhibited before.
David J. Slater, a British wildlife photographer, was shooting in one of Indonesia's national parks when the mischievous black-crested macaque snatched his camera equipment and became enthralled with the reflection in the camera lens. Slater shoots wildlife with a Canon EOS 5D Mark II and his DSLR lens was large enough for a clear reflection.
The macaque shot a couple hundred pictures before Slater was able to recover the equipment. And while many of the shots were out of focus, the majority of the pictures showed the monkeys showing off their teeth as it’s likely the first time they had seen their reflections. Slater said that the group of monkeys was initially frightened by the clicking sounds of the camera, but they all eventually returned to check out the gear.
Inadvertent or not, I'd still rank it as one of the most powerful and moving photographic self-portraits.
Here is the un-cropped image:
