My densitometer died. I've got enough experience to make do with a "proper proof" but.......Has anyone ever determined an accurate, repeatable method of using a scanner as a densitometer for B&W? I feel like it could be done but haven't figured out a way to create a standard and so never got past the "I wonder" stage.

I suppose you could start with an ICC target? To calibrate your scanner and then use measurements off the grayscale part of the target to check against the densities on your b&w negative? Except of course the target is a positive with relatively short Dynamic Range and the neg is a negative.

Hmmmm. any thoughts?
