The winners of an annual competition of underwater photography have been announced in Florida. See the winning entries here.
Hundreds of stunning photos from a record number of entries made this year's shortlist, all of which will be displayed in London in April.
Photographer Sergey Semenov has captured breathtaking panoramic pictures of New York by stitching together thousands of images of the city.
San Diego resident Anton Orlov paid $100 (£62) for the vintage 1901 Bellini Jumelle camera, but while cleaning it he found he had purchased much more than a camera.
There were eight developed photographs inside the casing depicting scenes from the First World War including planes, ruins and even a bomb.
Orlov currently has no plans to sell the pictures, saying: “I'm just happy to put them out there after them being hidden in a camera for 100 years. I'm just happy to see people enjoying them.”
