I’ve been wrestling with this question quite a bit over the last few years— worrying more about digital files than negs, but both nonetheless.
One conclusion I’ve reached is that family will tend to filter out images of people they know, and dicscard the rest.
Another conclusion is that digital files are inherently more susceptible to loss than negs— I currently maintain my digital archive backed up triplicates on 3 external drives, stored in 3 locations, and I replace the drives at regular intervals. But, even if they’re maintained by me, no guarantee anyone else will when considering descent of multiple generations. And that’s IF someone is inclined to look through them.
So, I think we face 2 issues— survival of our images in general and survival of “art work” vs strictly family images.
Prints offer a solution to the former, but not the latter.
So, I think I’ve arrived at at least a semi-adequate solution. I am going through my archives, choosing images to print in high quality books— think linen covers and matching slip boxes, etc. I’m going to mix family stuff, the best of it, WITH my best artwork.
If future generations want the family history, they can bear the burden of a few art shots too!
