A method for producing a set of exposed photographic colour negatives and the use of said set of negatives in a method for calibrating a developing and a printing machine system for making photographic colour prints

摘要

A method has been found for producing a set of exposed photographic colour negatives for use in calibrating a developing and a printing machine system for making photographic colour prints, whereinall the exposures are carried out to the same multicoloured object which also contains a grey reference part while using the same type of photosensitive film material, andthe exposures comprise at least 8 normal (N) exposures, at least 4 over (O) exposures and at least 4 under (U) exposures, at a ratio of the number of N/O/U exposures of 5/(2-3)/(2-3), and include, in the order given, each of the four sequences NN/NN; NN/OO; NN/UU; and UU/OO, or NN/NN, NN/UU; NN/OO and OO/UU. The set of exposed negatives thus produced is used in a method for calibrating a developing and a printing machine system for making photographic colour prints.
