Color negative films with non-linear characteristic curve shape for telecine transfer applications

摘要

Color negative photographic films having red, green and blue color sensitive records, wherein the ratio of the toe area contrast to the mid- scale contrast for each of the red, green and blue color records is less than or equal to 0.80, and either at least two color records having a toe- area contrast less than or equal to 0.42 or a mid-scale contrast less than or equal to 0.55, or the film having a speed rating of ISO 200 or greater. The mid-scale contrast for a color record is defined as the slope of a straight line connecting a point C and and a point D on the characteristic curve of Status M density versus log Exposure for the color record, where points C and D are located by defining a point A on the characteristic curve at a density level 0.1 above minimum density, a point B is located on the characteristic curve at an exposure value +1.0 Log Exposure beyond point A, and points C and D are located at exposure values -0.45 log Exposure and +0.45 log Exposure with respect to point B, respectively. The toe-area contrast is the slope of a straight line connecting a point E and a point F on the characteristic curve, where point E is located at (mid-scale contrast)/6 density units above minimum density, and point F is located at 0.3 log Exposure higher in exposure on the characteristic curve than point E. Use of such a color negative films are particularly advantageous in making telecine transfers.
