I believe that the Surrealists would have worshipped Photoshop as a minor god. It’s only function is to distort reality. Reality is distorted enough by the lens which – apart from the focal lengths closest to that of the human eye – shows us a view of the world which we cannot see with our basic vision.
Photoshop takes these already unreal images and allows almost limitless manipulation. Combination and/or juxtaposition of disparate images can conjure worlds or visions we may never have imagined.
