Known as a 'Moonbow', the hypnotic phenomenon was captured under the gaze of a full moon over 'The Devils Cataract' section of the falls.
Photographer and television presenter Charlie Hamilton James travelled to Cataract Island on the Zambezi River between Zimbabwe and Zambia, where he managed to observe this rarely witnessed event.
SO HOW IS A MOONBOW CREATED?
Moonbows are most easily viewed when the Moon is nearly full. They are relatively rare because they need a number of conditions to appear. The Moon must be less than 42 degrees high in a very dark sky.
‘The photos of moon rainbows over The Devils Cataract are probably the first ever taken,’ said 38-year-old Charlie, from the West Country.
‘Victoria Falls is also known as "the smoke that thunders" because it creates such a huge spray of water - up to a mile high. This is obviously perfect conditions for rainbows - both day and night rainbows.
‘We took them from Cataract Island in Zimbabwe and I spent several nights shooting more time lapses and also still images.’
Rarely photographed, Moonbows are common events that reveal themselves at the most unsociable times.
‘Moon rainbows are not a rare phenomenon you just need the conditions - large amounts of spray and a full moon,’ said Charlie. ‘I'm sure moon rainbows happen all over the place but most will be too faint to see. Victoria Falls is one of the largest falls on earth and so creates the massive amounts of spray needed.’
Spectacular when photographed, the Moonbow was in fact underwhelming to the naked eye.
‘Funnily enough it’s not too impressive to the naked eye, it's just a faint white milky arc with no colour in it,’ said Charlie.
