I have determined I need a surfactant to get my paper properly coated. Will photoflo work? Also does one add it to my total supply of sensitizer or to just what I intend to put on the paper. Also will It help to add it to my salt solution? I ask this because I am having a hard time getting my slat prints to come out well. Right now they come out real blotchy in spots and a very light mauve in others. So I figured my problem is that either the sensitizer, the salt solution or both are not penetrating or sloughing off during coating. I suspect my salt is soulghing off when I coat with the sensitizer as the edges of the coating outside of the negative are a very red brown and grainy yet the areas that come out right and a very cool brown also I just checked some salted paper and noticed that the surface feels gritty! Any thoughts?
