Amazing white rainbow snapped over Scottish moor
BBC Nov 22, 2016
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.
He said: "It was quite amazing."
