小编摘要:英国的一位摄影师花了十年时间来拍摄珊瑚,但大多都失去了艳丽的色彩。近日,他发现,将蓝色光束照射在这些珊瑚上之后,效果将大大不同。

导读:英国摄影师Louise Murray花了十年的时间来拍摄珊瑚,但大多数在肉眼看来都显出棕褐色且暗淡无光。但当摄影师将蓝色的光束照射它们时,一切就显得完全不一样了。“就像走在6月午夜的牛津街上与走在被圣诞灯光照亮的牛津街上的区别”。

Louise Murray has spent a decade photographing corals - most of which appear dull and brown to the naked eye.

But when the photographer shines a blue torch on them, 'It's like the difference between walking down Oxford Street at midnight in June, and walking down when all the Christmas lights are on.'

'It blows you away completely the first time.' Murray works with scientists who believe the weird effect could be a sort of 'sunscreen' to help protect the animals from being bleached.

The wildlife photographer uses a powerful blue light to stimulate photosensitive pigments in the marine life, which then emit fluorescent colours. The creatures also respond to UV light - but Murray gets better results using blue. She wears a yellow mask while diving to see the colours more clearly.

Louise explains: 'Almost all these photographs were shot after dark as the sunlight masks the colours.'

'The stronger the light the better the results, I have to filter my camera and eyes with a yellow mask so the true colours are revealed.'

'The pigments are photo-pigments, they respond to being flooded with blue light by emitting

their own colours - both the coral animals and the plant.'

Scientists suspect that it's a defence against being bleached by the sun.

Her latest collection was captured while diving in the dark waters of Tondoba Bay in the Red Sea of Egypt.

Louise first started capturing the fluorescent colours of marine wildlife over a decade ago.

She said: "I love doing it, the colours still blow me away, and scientists are still trying to come up with an explanation for their purpose.

"On land peacocks use fluorescent pigments to make themselves more colourful and sexy to the opposite sex, which could be part of the story for some of these fish.'
