As far as natural phenomenons go, it is one of the most spectacular.

These images capture the moment a waterfall in Yosemite National Park turns into a beautiful fountain of colour.

A rainbow forms in the spray emitted by the California waterfall, creating a dazzling effect.

The natural wonder was captured by photographer Justin Lee, who was overjoyed to find himself in exactly the right place at the right time.

Mr Lee, from British Columbia, Canada, was standing close to a cliff at the Tunnel View lookout when he spotted the colourful scene.

He said: 'The sun has to be in position to get the rainbow, and this photo was not planned by me beforehand. I just happened to be in the right place at the right time.

'I couldn't believe how lucky I was to see such a sight, and just had to start taking pictures straight away.'

Mr Lee took hundreds of photos of the magical event.

He said: 'I was there for about 30 minutes, snapping probably a couple of hundred photos at this particular location.

'I am a semi-professional photographer, although I am more a portrait and wedding photographer than a landscape photographer.

'I am inspired by the quality of light and colours, and Ansel Adams, one of the most famous photographers to have ever lived, who made his name at Yosemite National.'

The ideal conditions for a rainbow are the combination of sunlight and water droplets.

This usually comes in the form of rain, but fine spray from a waterfall is often just as effective. SOURCE
