The photos are kept in albums inside plastic sleeves. What he does to preserve them is to take the photos out of their sleeves every few months and keep them outside for a few hours in a dry place. He makes sure his hands are clean and dry before he handles the photos.Then he puts the pictures back in the albums. He has done this diligently over the years.

This already seems impractical in most of the world... I'm not really sure how you'd ensure that in an affordable way - and the article doesn't really offer any advice. Maybe if you get some special sleeve that keeps the inside dry, and then place the photos in your refrigerator?
Does anyone know of a scanner that does better than 600dpi that isn't insanely expensive? High quality photos can have extreme details that 600 dpi can't capture.
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?
