Stoeckler's 2-Bath Film Developer
Probably the simplest 2-bath developer to make and use. - incredibly cheap, too!
Bath A Metol: 5 g Sodium Sulphite: 100g Water to 1 Litre Bath B Borax: 10g Water to 1 Litre Mix in the order given in about 3/4 the total volume of water at about 35-40DegC. Make sure all the Metol is fully dissolved before adding the Sodium Sulphite. Make up the total volume with cold water. To use pour Part A into the tank and agitate continuously for 4 - 5 minutes. Drain the tank thoroughly and immediately (do not rinse or use stop bath)pour in Part B, but DO NOT AGITATE. After 4-5 mins in part B pour out, stop (or rinse) fix and wash as normal. This works because the developing agent (Metol) is absorbed into the emulsion during the first bath, where little development takes place. Part B is an accellerator, which immediately works rapidly in the highlight areas, where because there is no agitation the developer is exhausted rapidly, preventing the highlights blocking up. The shadow areas continue to build slowly until all the absorbed developer is exhausted, giving a very printable negative with excelent highlight and shadow detail and well-separated mid-tones. Temperature is not critical but this works best at 20degC . A few other useful tips:
