I think that when one works in a studio under controlled light (catalogue work or things like that) it's not uncommon that film is used on its linear part of the characteristic curve, where slide film can be on par with negative film. I don't know about how exact can slide film be in their "best" part of the characteristic curve. I didn't scan negatives a lot, but I did discover that's a lot of head scratching involved when filtering without a reference, at least a neutral grey. Professionals working in a colour "managed" environment use colour charts as a matter of fact and might prefer negative film. It's not the shop fault, it's the medium. Tourists don't put colour references in their shots and they happen to be disappointed by the prints they receive from the shop. Negative films sadly need a colour reference.

The general problem with negative film is that if there is no colour reference in the picture (if there is no test frame with a known colour patch target) then the 1-hour printer is left in the cold about filtration, and takes all the brown stuff when the result is disappointing the client.

For a "typical" customer without a darkroom or money to pay a pro, shooting slide film was one of the ways to skip those automatic, unmaintained machines run by untrained operators. The original cause for the myth are the automatic 1-hr labs that autoadjusted color neg images, trying to make "average customer" satisfied. Unfortunately, this farce has thrown some gasoline on the flames of the traditional myth of color-inaccurate negative film. There are some pieces of broken hardware and software sold to customers with a label of "scanner", causing the color-CORRECTING orange mask to actually cause color errors, but that is a different story. If you ever sc*n your images, this is instantly obvious the slides always show some crossover and other color problems, whereas negative image is pure and clinical. The reason why slide films were preferred in some situations when accurate colors were needed were mostly non-technical choices made by non-technical people and that's perfectly fine but that still does not change the truth.Īlso, the accuracy of slide films has not progressed at all in the last decade or so, but the color negatives have advanced more. If I want accurate look and don't have any preference of the output medium (slide/negative) (in practice, if I'm going to scan them), then I naturally pick color negative, which can be in order of 10-100x more "accurate". I'm a big fan of slide films, but I like to state the real reason I like them, and it's completely opposite from being "accurate". Mostly, the reason slide films are considered more "saturated" than negatives, is not the saturation itself, but a combination of high contrast and severe color errors - because color errors create color in scenes that otherwise looked dull gray! For example, in landscape images, certain color crossovers may render the images more appealing and a look of higher saturation. This is also one of the reasons people use slide film - they have a more interesting "color palette" or "look" to them, exactly due to these color errors. These problems are practically non-existent in color negative films, with at least 10x or so more linearity and much more color purity because of masking. The dyes are unmasked and produce unwanted absorptions. RGB curves are all far from linear and differ in shape for every color record.

Slide films are completely based on HUGE color errors. You can verify this very easily from the curve sets. Any color neg film is much more accurate in color than any color slide film from obvious technical reasons.
