Is this the developer that is supposed to be replacing Ilfosol S, due to short shelf-life? Is it supposed to have the same characteristics? The reason I ask is because I am currently using Ilfosol S for my FP4+ in 35mm and MF, and I want to get some BTZS testing done on some 5x7 film before I start shooting LF and wasting too much film. I'm sticking with FP4+ for the time being, as I'm somewhat familiar with it, but I don't want to spend the money on film testing with Ilfosol S if it is going to be replaced soon. Is there another developer somebody could suggest for this film in 5x7 (I will be contact printing only, with a diffuser head for the time being)? I want to continue with the Ilford line of products, and I don't shoot alot, so I would also prefer to stick with a liquid concentrate, rather than going to a powder.
Thanks,
Tim
