'Quadruple rainbow' caught on film for the first time

The third (l) and fourth (r) rainbows appear closer to the sun, rather than opposite it as with the first and second, which would have been behind the photographer
Scientists have captured the first image of a "quaternary" rainbow - the fourth rainbow caused by the bending of light through water in the air.
