On the other hand none was really terrible. If you need true ISO 400 speed in a colour transparency film here they are, ranked in order of my preference. Please note that these are subjective evaluations. I realize that the frames with the geese that I've used to evaluate graininess are too small and too low-res here on the web for you to judge much yourself. You'll simply have to trust my observations.
Colour saturation is low, but grain is very low and contrast was fine.
Subjectively this film performed the best at ISO 400 of all the films tested. I've used this film before at ISO 100 and was not impressed with it when used at that speed. But at ISO 400 it did very well just behind the Agfa emulsion. ISO 400 needs. This is by far the grainiest of the size films tested, but ranked very well in terms of contrast, colour balance and saturation.
