I'm apparently a bum because I can't afford a real 8x10 camera so I've constructed an 8x10 wide angle pinhole camera. I want to coat 8x10 glass and use it as a negative but the liquid emulsions I've tried off the shelf are crap! in my opinion. I want to make my own but cant find the silver nitrate. Anyone know a cheap source for it? Is silver halide cheaper and would it work? Cliff
