The real issue comes down to, if your scanning a 4x5 negative, and then post processessing, do you need to store the files forever on the computer? As long as you still have the negative, then you can always rescan and repeat the processing can be done again, to give a new result. When I did printing is the darkroom, I rarely kept printing notes, other then that on the back of the contact print, so I knew where to start from. This was often because, the print I wanted 6 months or 3-4 years later might be very different, considering the mood I was in. We sometimes forget in print photograpy that, like music and theatre, the art is double staged, the negative (or initial digital image) is the symphony (or script), the print is the performance. W
