When I'm hanging out with my grandchildren I let them use my small point-n-shoot. Because Hazel (in photo here) will take a turn, then Ellery will have a turn, I wasn't able to tell which photos belonged to which girl. Because I like to print off a few of their shots to give to them, I came up with the idea of self portraits as a way of identifying the photographs.
New rule: as they pass the camera off, the new "photographer" must take a self portrait, thus identifying the photos that follow. I figured they'd do feet, hands, part of a dress, but Hazel turned the camera on herself and did this self-portrait. Luckily I was standing there with my camera handy.
