Not that it ranks up there with that shot of the South Vietnamese guy paying out what he thought was righteous (and quick) justice, but I wonder, in this age of the Internet, if this might become just as well known. It will certainly be known by lots of people more quickly.
The story, in case you’re interested, is that Melissa Brandts and her husband were hiking in Banff National Park in Alberta, Canada. They decided to take a portrait of themselves with Lake Minnewanka in the background (no doubt for the annual “look at the cool places we went and you didn’t” holiday letter). Melissa set up the camera and went back to pose, and her husband held the remote shutter release.
Meanwhile, attracted by the sounds of the autofocus, an inquisitive Columbian ground squirrel, common in the park, popped up to investigate. Click! “Self-Portrait With Ground Squirrel” was born.
Personally, I think it should still make the holiday card, even though by then, everyone will have already seen it.
