This list has been compiled from data sheets that I've accumulated over the years, and shows the recommended processing times for a wide range of films in a wide range of developers. The recommended agitation routine is also shown, along with an indication of the resulting negative contrast, and the source of the information. Note that these times should be treated as starting points only. Consistency is everything. Avoid development times shorter than four minutes.
More development means more contrast.
Less development means less contrast. There are no rules in this game. Do whatever you have to do to get the results that you want. For consistency, manufacturers' recommendations are preferable, but personal processing times will be included when nothing else is available. End of Forwarded Message .
