Everyone knows you don't get pictures of rainbows this beautiful, without sacrificing a few leprechauns. Like, seriously, at least 100 of the little guys.
The technicolor massacre occurred at the base of Yosemite National Park's Bridalveil fall. Though photographer Justin Lee (who captured the carnage on film), would have you believe there were other, less violent, so-called "scientific" factors involved... factors like "light," "water droplets" and "refraction":
The sun has to be in position to get the rainbow, and this photo was not planned by me beforehand. I just happened to be in the right place at the right time…I couldn't believe how lucky I was to see such a sight, and just had to start taking pictures straight away.
Whatever helps you sleep at night, leprechaun killer.
