I dont know if my answer will be of some help, i know that for this kind of problem the solution is to take the picture with close a colour reference (like kodak strip of paper with colors references) or just a white reference ( gluing on a piece of paper some powder of barium idroxide, that is the most white thing on earth). Once you have it , it is easy to calculate using Photoshop or any other software the RGB quality of the white reference area on your negative and make color corrections. bye
