I'm curious to hear if anyone out there has had experiences with developing phot ographic paper in film developers, and what differences there are in the final r esult. The main reason I ask is because I saw the formula for Gainer's Vitamin C Film Developer, which is extremely simple and inexpensive to mix, and seems to bee less toxic and allergenic than other developers out there. I'm most intere sted in this particular developer, of course, but I'm also interested in hearing about other developers. Side question: does anyone out there know how long the shelf life of this develo per is?
