Roderick Mann (link) setup a GoPro Hero 3 Black Edition on a makeshift stand, put it into one second-per-frame time lapse mode, and happened to capture a full cycle of a rainbow. He wanted to capture the last bit of sunlight, but was blessed with a little something extra.
It wasn’t until I got back to the house that I realized what I had captured. I wish I had let the camera run longer.
