The 50th Wildlife Photographer of the Year competition opens on 9 December 2013.
The competition remains the most prestigious wildlife photography contest in the world, championing the ethical discovery and enjoyment of the natural world through the power of photography. To be in with a chance of seizing one of the coveted awards and grand titles, entries must display creativity, innovation, authenticity and technical excellence.
Amateur and professional photographers alike are invited to submit images to 18 categories, with four categories open exclusively to those aged 17 and under.
Judges are looking for images that capture the beauty, mystery, fragility and diversity of life on our planet. They should interpret the familiar in new ways and give a voice to subjects, places and issues that may otherwise go unnoticed.
New for the 50th competition is the introduction of a revised category structure, new awards, including the Wildlife Photographer of the Year Portfolio Award; the debut of new technologies such as time lapse photography; and a new category, WILD-I, for mobile device led content.
Photographers compete for one of two coveted grand titles, plus a share of a prize pot worth £50,000, and the opportunity to be featured in an exhibition that debuts at the Natural History Museum in London before touring six continents.
The competition closes on 27 February 2014. For more information, take a look at the Wildlife Photographer of the Year
