A photography enthusiast has walked away with a first prize in this year?s Visions of Science Photographic Awards after winning runner-up places for the past two years.

It was third time lucky for retired executive Jim Greenfield who claimed top spot in the Science in Action section of this year?s contest and bagged himself £1,000 cash.

Jim used a Nikon F90x 35mm SLR to capture his winning image which depicts a tiny shrimp entering the mouth of a fish ?to clean its teeth? of harmful parasites.

Jim said he shot the picture at a depth of 10m using a 105mm macro lens and two flashguns while diving off the coast of the Caribbean island of Curaçao in the Netherlands Antilles.

Also among those flying the flag for amateurs was Robert Anderson who won first prize in the Einstein Year Award with an image showing how the surface tension of water can support even a metal paperclip.

He has donated his £500 prize to the Disabled Photographers’ Society.

This contest ? organised by the Daily Telegraph and healthcare company Novartis – attracted more than 2,200 entries ? 60% more than last year.

For details on more of this year?s winners keep an eye out for future issues of AP, in shops every Tuesday.
