Colin Leonhardt captured the holy grail of aerial photography on his latest photo shoot: a perfect circle rainbow.
Leonhardt, 46, who specializes in aerial photographer, was flying back from a photo shoot when the pilot of the plane he was on flew over Cottesloe Beach in western Australia during a rain shower.
The rare phenomenon of a circular rainbow can only be seen from the air, when the sun is shining from behind the observer through droplets of rain.
