This is related to as question I asked in another thread, but the nature of the question has diverged from gear to digital processing.
Situtation: I'm trying to scan three negatives that are shot at three different exposure settings to test the dynamic range of film.
Problem: When the scanner scans it, the software automatically adjusts it for optimal scanning, which over compensates and makes three exposures look relatively equal.
How can I scan the three negatives at the same exposure settings? I've tried adjusting contrast and brightness, but I believe that only gets me so far. Is there something I can do that is more percise?
