After my recent success with TMX, I delved into my freezerful of film\nand pulled out a roll of Pan F I want to shoot. But I'm a bit mystified\nby the enclosed processing instructions.\n\nWas thinking of using D-76, and they have times for both this and ID-11\n(same times, since the same developer, except that they list ID-11 at\n1+1 but not D-76, though I assume I can also dilute it). But they show\nthe same times for both ISO 25 and 50 exposure. Can this be correct?\nOther developers show different times for the two speeds.\n\nThey also show times for Perceptol, but not Microdol-X. Richard K., you\nsaid these developers were equivalent: would you use the same times for\nboth of these? The Humumgous Massive Really Really Big Dev Chart\n([URL]http://www.digitaltruth.com/devchart.php[/URL]) shows different times for\nthese (9 min. for Perceptol vs 12 min. for Microdol; should I just use\ntheir recommendations?
