I read these fast, so I might have missed it, but no one is mentioning CMYK printing. That is what all this is about.
If you're working with a good printer, especially one who reproduces fine art images on a regular basis, your color workflow will be guided by them. Color scales in the film will help you with selecting the best exposure as well as creating a balanced scan. Color targets in direct capture images will assist the software in creating a balanced image. Both targets matter to the color separator who is converting your file to CMYK. And, if your workflow allows it, you are "hard proofing" the CMYK print against the actual work under controlled lighting conditions.
