This breathtaking photograph of an unusual white rainbow has been captured in a remote part of Scotland.
The beautiful sight was spotted by a man out walking in the snowy moors, far from the gales of Storm Angus, on Sunday.
Known also as a 'fogbow', the image from Rannoch Moor in the west of Scotland was captured by Melvin Nicholson.

Out walking on the moor, south of Glen Coe, he said the "unbelievably beautiful" white rainbow appeared before him.
Mr Nicholson said: "It is a colourless rainbow that is made up of tiny water droplets that cause fog.
"It's an amazing thing to witness and can generally only be seen if the sun is behind you when you are looking at it."
He said an isolated windswept tree, framed by the fog bow, completed the shot.
"It was just beyond magical and one of those days that you'll remember for a long time to come," he added.
A fog bow is a similar phenomenon to a rainbow; however, as its name suggests, it appears as a bow in fog rather than rain.Because of the very small size of water droplets that cause fog - smaller than 0.05mm - the fog bow has only very weak colors, with a red outer edge and bluish inner edge.
