During the Iceland trip, my friends noticed a spectacular waterfall, so we stopped. The waterfall was Goðafoss, and we went to take some photos. I wanted to take one with me in it, so I set up the camera on the tripod, framed the shot, adjusted the settings and ran over to the edge of the cliff and posed, while a friend was waiting to press the shutter.
I'm standing that far back because I'm afraid of heights. Still looks cool, though.
