IS 10329 : 1982 Method for sensitometry of photographic papers

1 Scope

1.1 This standard prescribes a method of determining certainsensitometric characteristics of developing-out black-and-whitephotographic papers intended for contact or projection printing ofphotographic negatives. It specifies the exposing and processingconditions to be used in determining thedensity-versus-log-exposure curve of the photographic papers. Italso specifies procedures for deriving numerical values for suchsignificant sensitometric characteristics as speed, maximumshoulder density, density range, and log exposure range.
