Planning to build a bag bellows for my monorail 4x5 camera. How important is the inside surface? Does a slight sheen to the fabric cause concern? I got thinking about all the space inside the view camera bellows and compared that to the len ghts medium format camera makers go to by adding baffles in the body. Is there a ny concern with a view camera about similar internal reflections? Do bag bellows inherently produce more flare than a pleated bellows?
