The Technology of Enhanced Color Saturation

SMPTE Journal, April 2001 K Ektachrome 100D color reversal film/5285 was introduced to the motion picture market in December 1999. Its release marked the culmination of a number of years of work on the part of researchers in both Kodak’s Color Reversal and Entertainment Imaging R&D groups. The design concept was to create a highly saturated color reversal film at an EI100 speed without compromising flesh and neutral reproductions. A total of three films incorporating the high color technology have been introduced by Kodak: Professional Ektachrome film E100VS for the professional still photography market, Elite chrome extra color 100 film for the consumer still photography market, and Ektachrome 100D color reversal film for the motion picture market. A summary of general performance attributes of the three films can be found in Table 1. Table 2 shows the characteristic curve comparisons between camera positive 100D film and camera negative Eastman EXR 50D film/5245 printed to a positive on Kodak Vision color print film/2383 (the only fair sensitometric comparison of a negative film and a positive film requires the negative be printed).
