ABSTRACT:
A color negative photographic film with at least one color record thereof having a mid-scale contrast less than or equal to 0.45, wherein the mid-scale contrast for the 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 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. Use of such a color negative film is particularly advantageous in making telecine transfers.
