Apparently, since 2004 Michael David Murphy has been posting the photos he didn't take. Michael describes his site like this:
Unphotographable is a catalog of exceptional mistakes. Photos never taken that weren't meant to be forgotten. Opportunities missed. Simple failures. Occasions when I wished I'd taken the picture, or not forgotten the camera, or had been brave enough to click the shutter.
In the place of these mistakes he writes a short description, often vivid and moving in their own right.
