Ilfosol-3 Film Developer is an enhanced, one-shot updated version of Ilford's Ilfosol-S. It has been created to suit the needs of photographers who prefer to use slower speed films such as Pan-F, FP4 Plus and Delta 100 Professional.
This is a fine grain and ultra sharp developer when used with films processed at full speed. However, you may use it at a 1:14 dilution for other films with only a minimal loss of image quality. It is supplied as a concentrate in economical 500ml bottles and is diluted (typically at a ratio of 1:9) for one-shot use.
