ILFORD ILFOSOL 3 black and white film developer is an enhanced formulation of the original one-shot, general-purpose, liquid black and white film developer ILFOSOL S. The new developer is particularly suited for use with medium and slow speed films such as PAN F PLUS, FP4 PLUS and DELTA 100 PROFESSIONAL where it ensures a fine grain and optimal sharpness at full film speed.

ILFOSOL 3 is supplied as a concentrate in economical 500ml bottles and is diluted (typically at a ratio of 1:9) for one-shot use. However, for greater economy, ILFOSOL 3 can also be used with many films at a higher dilution of 1:14 with only a small trade off in image quality. The concentrate once opened has extended keeping properties, so Ilfosol 3 is a good choice for occasional use.
