The amount of manipulation is certainly evident in both photographers work, but in both cases I find their restraint comendible, and their skill impressive. It goes to show you there are advantages and diadvantges to every film format. Try getting those kinds of reults (speaking of burning and dodging) while contact printing. Nothing like a nicely projected negative to allow for precise control as far as the darkroom manipulations are concerned.
