Albulena Panduri (blue-a on Deviant Art) has created some absolutely stunning photo manipulations. Each one grabs you and draws you into a surreal and beautiful new world. I couldn't help but stare in awe at all of her fantasy worlds. I highly suggest checking out the rest of her gallery if you get a chance.
Jean Francois Rauzier's hyperphotos might look like a single photo, but these self dubbed hyperphotos are made of hundreds and sometimes thousands of individual photos. You can dive into each one and find an incredible amount of detail. Rauzier spends countless hours collecting and stitching together photos until it is impossible to distinguish between them. Make sure to check out the incredible full resolution photos at his portfolio.
