I was coming back from shooting in the Everglades, and as I passed some farms near Florida City, Florida, I saw this irrigation truck at the end of the field, with a rainbow in the spray of water. I pulled over, and took this shot before the truck moved,the angle changed, and the rainbow disappeared. Nikon D-7100 with a Sigma 28-300mm lens @ 28mm. ISO 160, 1/250 @ f-8.
