Drew, that "bad" example with cyan, grape and pumpkin was only intended as an example. NO Kodak film, or any film I know of, was produced without interlayers and scavengers. Even the earliest Agfa color negative film had interlayers and scavengers.

I don't know what films you used in the past but they all had pretty good correction as well as good grain and sharpness. Recent films such as Ektar and Portr are far far better.
