I have a chart that shows reciprocity failure adjustments for various black and white films. This chart also suggests decreasing development times as exposure times increase. The reasoning is that reciprocity failure affects the shadow areas more than the highlight areas. Is this correct? I also have a pinhole time calculator that suggests INCREASING development times as exposure times increase. Which is correct? (Excuse the cross-posting if you read alt-photo-process and pinhole-discussion.)
