Photographer Daniel Beltrá has often worked with us on forest and climate campaigns. He has just won the new Prince's Rainforests Project Award at the prestigious Sony World Photography Awards, and many of the prize-winning photos were taken while he was working on our campaigns in the Amazon and Indonesian rainforests.

One of the pleasures of working at Greenpeace is having access to a truly incredible photo library and there's been more than one occasion when, looking for images to accompany a blog story, I've become lost in the wealth of powerful and affecting images.

The photographers who supply us with these photos are rewarded for their work with the occasional trophy and Daniel Beltra, who has accompanied Greenpeace campaigners on expeditions all over the world, was last week presented with the Global Vision Award for photos he took in the Amazon as part of Pictures of the Year International. He also received an Award of Excellence in the Science/Nature category for a collection from the Antarctic, taken during last year's Southern Ocean expedition on the Esperanza.
