Inverted drawings in charcoal and oil based pencil on cotton paper. Photographed in full format and retouched in photoshop then printed on high quality digital paper :) They always tell you to draw the negative space so why not the whole thing! I think I kind of invented this technique or at least refined it. I dont know of many others that do this? Its very rewarding when it comes to rendering light and detail such as hair,,, Thank you and stay geeky! (Prints available in link)
