At one time there were some members on this site sharing some lovely photos. I'm hoping to get some information here now that I'm working on getting a number of old family slides (thousands?) into digital files.
First, some of the slides just didn't age well. Some of them have contracted a fungus, others have not held their color over the last 50 years. I'm assuming those will be difficult or impossible to restore at home, though a professional might be able to do something.
Second, I'd like some input on scanning resolution and file size. Part of the reason I'm digitizing these files is so that unique slides can be shared with all my siblings. I doubt that there will be any attempt to create large prints, and probably no attempt to broadcast or show large scale projections from these files. By the way, this is 35 mm color positive slide film. The scanner I have produces a roughly 2.5 Mb file, and a resolution of 5472x3648. Any opinion on whether this is a sufficiently high resolution?
Third, the scanner is capable of doing some exposure correction during the scanning process. However, it does require user input which means I can't simply insert a slide, push a button, then insert the next slide. Instead, I would have to insert a slide, evaluate the exposure on the rather small (and directional) screen, make any corrections to exposure, scan the slide, then insert and evaluate the next slide. Should I expend the extra effort to scan the slide correctly the first time, or can modern photo tools correct issues easily enough post-scanning?
I'll attach some scans shortly.
