I tend to agree with JordyArt about the tendency to hue & lighting to cause probs &c with surreal photo-art. It's so hard to replicate what nature makes and so often the pieces look like grandpa after surgery. IMO the most effective sur-REALity pieces are often 'enclosed' or 'flat plane' images that don't rely on multiple lighting factors. An enclosed one would be stuff like Tedz' 'pickled barbie' whilst flat plane ot indoor still lifes usually keep a constant shadow and are easier to work with. A surreal look can be given by distorting lighting elements as part of a alienating discordancy, so sometimes these rules all fall down anyway. Dali's work is interesting as he built his surreal pieces up, working on layer upon layer of paint... feeding the corporeality of the piece, making 'it' (something weird) look perfectly natural... the key is our subtle perceptions.
