The photofinisher did this for us in prints, but it s our job now. Digital color balance is easier than darkroom work, but color balance is harder for negatives than for prints or slides. The film scanner software has a Negative mode that does this, but the shade of orange varies among film brands, and even in different films from one manufacturer. Most film scanners offer a few film types to aid this. Slides have dramatic contrast, but not very good shadow or highlight detail.
Negatives capture greater scenic range, but store it compressed in less range on the film.
Negative film itself actually has lower overall dynamic range scanning requirements than slides, which makes life easier for inexpensive scanners. Images from both slides and negatives can only span tone values 0 to 255 in the 24 bit image. But because this greater range of scenic detail is compressed into that span on the negative, it offers more possibilities to expand selected regions, to favor the shadows or favor the highlights, to show maximum detail. We cannot favor both ends, but we can do either, by various brightness adjustments, and negative film offers more opportunities for photo manipulation. Chapters 20-23 have details.
