Your travel photography could earn you a £1,300 camera kit Our weekly Big Picture competition will reach its 200th round on April 21. To mark the occasion, we are giving away a Nikon D7000 camera and lens to the sender of the winning photograph, plus a voucher to attend a Nikon one-day photography course. The runner-up will receive a Coolpix S9100 worth £249.99. The 200th round will be judged by some of the most illustrious names in photography: Roy Robertson, photographer and president of the Royal Photographic Society; Philip Lee Harvey, an award-winning travel photographer whose work has taken him to more than 100 countries; Charlie Waite, one of the world's leading landscape photographers; and Joe Plimmer, national newspaper photographer and picture editor of the Telegraph's luxury travel magazine Ultratravel. The Big Picture began life in February 2008 as a fortnightly competition. However, so impressed were we by the standard of entries that it soon began appearing weekly and in January 2010 was moved to a more prominent position on the back page of the Telegraph's Saturday travel section. We have had tens of thousands of entries, including the dramatic image above of horses galloping in the Camargue region in France, which was sent in by Austin Thomas of St Helens, Merseyside, and first published in Telegraph Travel in June 2009. It won Mr Thomas round 55 of our competition, and later a Silver Medal from the Fédération Internationale de l'Art Photographique. Speaking in 2010, Mr Thomas advised other amateur photographers to be prepared to accept criticism and to take fewer, but better, photographs: "Decide what kind of picture you're looking for and then focus on getting it," he said. Charles Starmer-Smith, Telegraph Media Group's head of travel, said: "It is no secret that the advances in digital camera technology have helped to close the gap between amateur and professional photographers. But when we started the Big Picture competition in 2008, we were astounded by the variety and quality of the images we received from our well-travelled readers. Was it a one-off, we wondered. Far from it: every week we continue to receive hundreds of pictures that truly encapsulate all that is weird, wild and wonderful about the world of travel - and, with Nikon, we are delighted to mark the 200th round with a special prize that will be awarded by an esteemed panel of judges. How to enter If you have taken a photograph that captures the weird and wonderful in the world of travel, email it to thebigpicture@telegraph.co.uk. You must include a brief description of the photograph and your name, address and telephone number. The closing date for entries is midnight on Monday, April 16. We regret that we are unable to accept postal entries.
