Ilford ID-11 Film Developer can be used with all formats of black and white film to develop negatives with fine grain and sharpness for easy enlargement, without a loss of emulsion speed. ID-11 is packed as a powder and can be made up to a stock solution for normal tank or tray use, and can be further diluted 1+1 or 1+3 for photographers who desire longer development times, a higher degree of sharpness, and are willing to use ID -11 on a one-shot basis. One liter of working strength stock solution (not diluted) will process 10 rolls of 35mm/120 film. Diluted 1+1 it will process up to 5 rolls of 35/120 film. Storage time for an unopened full bottle of ID-11 Stock solution is 6 months. For half full bottles of stock solution storage time is 1 month. If stock is diluted it can only be used as a "one-shot" developer and should not be stored.
