Photo Forum / Film Photography / Darkroom / March 2004Farmer stain - depending on paper brand?
Application of Farmer (split and combined) to Agfa PE and baryta papers result in an ugly yellowish stain. Thiocarbamide is of no help. I wonder if there are some brands which allow highlight reduction by Farmer without staining. (I am not looking for alternatives like iodine, persufate, permanganate etc.) > Application of Farmer (split and combined) to Agfa PE and baryta > papers result in an ugly yellowish stain.

(I am not looking for alternatives like > iodine, persufate, permanganate etc.) Are you refixing the paper after using the reducer? Either form of Farmer's will leave some halide residue behind. You might also try clearing in a weak bisulfite (or metabisulfite) bath, which may remove the stain. The final fixing bath is still necessary.
