Response to Film developed in 130 paper developer

Chemstry is chemistry. Any reducing agent will develop latent images. The typical criterion for paper developers is to make them reasonably fast acting i.e., build density fast (becasue few people are likley to have the patience to wait 15 mins for each print). However, film developers do need to be formulated more carefully. The reason for this is that since the negative will be enlarged, you are concerned about things like grain and sharpness to a much greater degree than with paper developers (grain etc is inconsequential in paper). This would matter much more for smaller formats than larger formats. Cheers, DJ
