I would definitely try using a Flip-Pal scanner. The company’s website has a number of fantastic how-to videos showing you how to scan photos in albums and frames. It’s also a great addition to your tool kit. I just completed a similar project where the images were elevated. The scanner has a 1/4″ depth of field. I took the lid off and flipped it to scan. I used two black microfiber cleaning cloths to block out light on either side of the scanner (just in case). Did the trick.
