RE: Colour corrections filters:
Since you are correcting the light before it hits the negative, can't you just use gel filters? They seem fairly cheap on Amazon.

I remember the bad old days that enlargers would have a gel drawer in the head that fit between a heat absorbing glass plate, and the first condenser lens.

not exactly . . . the orange mask is the problem, it is not like a gel filter that paints the entire image with a colour that can be compensated for. As I understood it when I did a lot of work with negative film the mask exists in areas where there is no image developed by the dye couplers which makes corrections with filters not really work. There will always be uncorrectable colour issues as a result. I occaisionally processed colour transparency as a negative for special effects and you wind up with a negative without a colour correcting mask and it is really difficult to make an acceptable and colour correct print using filters because of the missing orange mask which was tuned to work with the paper used to enlarge onto. Brown blacks and crazy crossed curves .

Colour transparency can be copied with few problems by using filters in the light path.... no mask!
