paul_brenner1 Posted February 9, 2004 Share Posted February 9, 2004 I shot a roll of Ilford Pan F recently for the first time in a long time. In checking development times, Gordon Hutchings (in his first edition) indicates a time at 70 degrees of 12 minutes (??!??). In the "Film Developing Cookbook", the time is indicated as 7.5 minutes. After 30 years doing B&W, and 15 years of pursuing fine art B&W seriously, I've found that absolute precision is not as important as some folks might believe. However, we have a fairly big gap here! Based upon my experience with FP4+, the "Cookbook" time seems a lot closer to what I think is right. However, I'd be interested in thoughts. Thanks, Paul Link to comment Share on other sites More sharing options...
everheul Posted February 10, 2004 Share Posted February 10, 2004 Every time I've tried a new film in pmk, Gordon Hutchings times have been pretty much on the mark. Is the pmk formula in the "Film Developing Cookbook" the same concentration and combination of chemicals as GH recommends? If so, then I am at a loss for the huge difference.

magic1 Posted February 10, 2004 Share Posted February 10, 2004 Trust Gordon. I've used that time for Pan F & PMK with good results. Link to comment Share on other sites More sharing options...
photojim Posted February 10, 2004 Share Posted February 10, 2004 Just one note: Pan-F Plus doesn't stain very much. Don't worry about it. The negatives print beautifully. Link to comment Share on other sites More sharing options...
paul_brenner1 Posted February 10, 2004 Author Share Posted February 10, 2004 Thanks for the feedback. Since I posted my question, I went to web sources, including the Formulary. It indicates 9 minutes @ 70 degrees. That makes a lot of sense in relation to FP4+, listed as 10 minutes @ 70 degrees. I don't have a revised copy of Hutchings book, just the original (I really have been meaning to get a new copy!) I know that he revised several of his times recommendations, especially with Ilford film as it changed. 12 minutes was probably either a simple mis-print or for an earlier version of the film.

andre_noble4 Posted February 11, 2004 Share Posted February 11, 2004 PanF in Wimberly WD2D+ pyro using Wimberley's recommended development time of 7 minutes @68F, I got an ASA of 20/25 and very good results. Link to comment Share on other sites More sharing options...
