View Full Version : Seeking Reciprocity Failure Chart
Can anybody point me to a chart for reciprocity failure for Kodak Tmax & Tri-X f ilms? The Kodak film book only covers metered times of 100 seconds and less. I realize I'm going to have to run tests, but was wondering if there is a good se t of starting points for the longer times. Also: how do filters alter the equat ion, in general?
Erik, Check out Steve Simmons' view camera book. He's got a pretty comprehens ive set of reciprocity charts for all kinds and brands of films, particularly fo r longer exposure times. Some good info on filters too.
