The chemical processes involved at development and bleach stages sometimes show variations that are difficult to explain. The paper describes some work about those effects (e.g. amount of developer, influence of exhaustion, safetight used, ...) and some efforts to minimize variations by the use of microprocessor-controlled automatic development machinery. Some minor problems caused by commercially available and affordable items will be presented; some major problems when trying to build one's own equipment are discussed.
