PHOTOSHOP ARTISTS
If you look properly on the image. the image is separate he took the island photo some where and then he Photoshop the fish photo. Because fish is so big and the space for fish is not enough you can see the fish can't move around it only can stay in one place. The artist used Photoshop to make little mountain to be fish upper body and cut the fish body from second photo.
This image clearly shows that it has been edit by Photoshop. Artists who made this image is Erik Johansson. was born on April 1985 is a Swedish-born artist based in Prague who creates surreal images by recombining photographs and other materials. He captures ideas by combining images in new ways to create what looks like a real photograph, yet with logical inconsistencies to impart an effect of surrealism. Some finished images are the combination of "hundreds of original photographs" as well as raw materials, and Johansson spends dozens of hours using image manipulation software such as Adobe Photoshop to alter the image digitally and to illustrate his idea. Reporter Robert Krulwich wrote that Johansson creates a "meticulous fantasy" which is "part photograph, part construction, part drawing" with "so many layers of foolery in his images, you can't pull the illusion apart, it fits together so perfectly."
