I've been reading up on salted paper prints, and have just gotten the chemicals in to try a few ($30 for 10 grams of silver nitrate -- whew!). In my reading, I note that the general use is sodium chloride (canning or kosher salt, or technical grade) or ammonium chloride, or a mix of the two. I don't, however, see any mention of people using bromide salts for the salting step, and I wonder why. If I understand this side of things correctly, silver bromide is both more sensitive, and sensitive to longer wavelengths than silver chloride, which would give a much faster print, especially if exposed under light that isn't filtered to remove visible wavelengths. I got a pound of potassium bromide with my recent chemical order -- at the time, I think mostly because I'd forgotten that developers that call for this chemical mostly want tenths of a gram per liter, though I'd also be able to use it in rehalogenating bleach for redevelopment processes. However, a liter of 2% mixed salt solution, equal parts sodium chloride and potassium bromide, wouldn't need a huge amount of the more costly salt and ought to produce significantly faster salted paper. Has anyone tried this? Are there contrast problems, issues with printing-out failures, or other reasons not to use a bromide salt for salting the paper before sensitizing with silver nitrate solution? On a similar note, has anyone tried developing-out a latent image from much shorter exposures on salted paper?
