A Color Timing Method and Calculator for Subtractive Motion-Picture Printers

George T. Keene

Densities of a gray card held in the key light of each scene provide accurate information for predicting printing packs. This timing method has advantages over the full-frame integrated density method in certain cases. A slide-rule type calculator has been used to predict subtractive printer balances from gray-card densities with a timing accuracy of ±0.03 log E on the first trial in an Eastman Color Negative-Print system. Equations are included for using a matrix calculator for this purpose.
