I did a lil youtube search of him, and if I heard him right, he takes photographs of his subjects but then adjuts the image to his liking. He's still an artist ie. someone who wants to invoke a certain type of reaction from his audience, his medium is just a super-realistic one. This also gives his medium an advantage over pictures - the fact that he can manipulate the image so easily without losing any realism makes it a better way to get his message accross.
Chimera of Filth
A gruesome beast with dripping flesh
Clings to me as a sick fixture
My throbbing heart it gnawed apart
It stalks and hunts me through mirrors
