Ilford ilfosol 3 is a liquid concentrate black and white film developer formulated to exploit the full potential of conventional black and white film emulsions in all formats. It enables professionals and amateurs to economically develop small quantities of ilford and other films with ease and convenience. Ilfosol 3 is particularly suited to developing medium speed films such as fp4 plus and delta 100 professional. It gives fine grain and good sharpness with full film speed. Ilfosol 3 is supplied as a liquid concentrate normally diluted 19 for one-shot use. Dilute it immediately before use and discard directly after development. For greater economy it can be used with many films at a higher dilution of 114 with only a small trade off in image.
