Ektar 100 truly and thoroughly sucks and Kodak knows it but their best film engineers have since retired and Kodak doesn't care anymore. Color negative film peaked about 12 years ago when Kodak, Fuji, and Agfa were all still fully in the game. A lot of beautiful color emulsions have since departed. The Fuji NPH 400 is probably the best still in existence circa April 2013.
Kodak Ektar 100 is for young kids who and old fools who do not know what quality color silver halide images look like.
