How to Preserve Physical Photos

Related question: what's the best way to digitize a collection of physical photos for personal use?

I ran into this problem recently for a family reunion where we wanted a slideshow of photos that were decades old. The best solution was to manually scan them using Google Photoscan which involves taking a 5 pictures of each photo with a phone and letting the app remove reflection, perform skew correction, crop, etc. This resulted in better photos than just using the phone's default camera software, but it still took 10+ seconds for each photo.

Does anyone have an recommendation for at home photoscanners that would allow me to drop a stack of photos into it and have it automatically scan them? I found various devices on Amazon that target this use case but they all have drawbacks like low resolution or excessive manual work. Has anyone done this with their family's old photos?

Recently I scanned all 1,100 rolls of film that my father and I took, for a total of 31,600 frames. For the 35mm film I used a Nikon Super CoolScan 5000 ED, and for the medium format rolls I used an Epson Perfection 2480 photo scanner (flatbed). I had purchased these scanners about 20 years ago, but they are still going strong and produce great quality scans. They are slow and require manually feeding each strip of film; every frame takes about a minute to scan and process, especially if you enable filtering to enhance image quality. The Epson is also great at scanning prints, although I had negatives for most of what I scanned so I didn't need to scan many prints.

After scanning everything, my endgame was to look through all the images, copy the best into a separate folder, crop and edit them, and produce a book. I made a dozen copies of the book and mailed them to all my relatives. The original negs are stored safely away, and I have a hard drive (with multiple backups) available in the event somebody wants me to send them a scan.

Long story short, I would take the time to do it manually. Even with an automated scanner, the chances of things going wrong is fairly high, especially if your prints vary greatly in size and condition (bends, warps, etc.). Yes, it is a ton of work, but the end results are worth it. If 10+ seconds per photo is too much for you, just bite the bullet and send them out to a scanning service.
