I compared this formula to Ilfosol-s and found it signifantly sharper. It does not have sodium sulfite, as does Ilfosol-s, yet the grain is still very fine, with a nice, tight structure. If you like Ilfosol-s, I strongly recommend you give this a shot.(posted 8160 days ago)1:1:14 means, add 1 oz. "A" to 1 oz. of "B" to 14 oz. of water.
