About a year ago, I started scannoing my archive of about 1000 rolls of film, dating back to 1977.
A mix of color and black and white, slide and negative, 35mm and 120.
A daunting task, but I started wjen I noticed some of my slides going mouldy and the colors shifting.
First I made an excel spreadsheet row for eaach roll with some basic information. Now I'm doing the scanning, about 1 roll per week (on average) due to lack of free time, starting with the most vulnarable color materials first.
So this will take me years to complete at the current rate. I hope to have more time once my kids grow up a bit.
As mentioned above, I put a considerable amount of the time into evaluating the frames and deciding which are worth scanning. The number of keepers per roll varies widely depending on if the roll was of friends/family or one of my "artistic efforts".
I try to multitask and listen to music at the same time. The results are worth it. I love film and still generate plenty of new "scanner fodder" each year. This is all part of a process, steps taken within a life-long hobby.
If you really can't get into some kind of groove with it, then I agree with posters above - it may make sense for you to migrate to digital capture.
Good luck in any case.
