Austin Sandmeyer- Thinker/Student/RockstarI'd recommend PhotoScan too... Will take you time but you have no worries around losing them along the way.
Product Pearson- Product Manager @ Property4MediaReally good app. Scans well and doesn't have the flash/glare issue that other apps seems to due to an algorithm that removes it. It's clever, but takes time if you have lots and lots of photos.
Anshuman Chadda- MD MPH; Physician EntrepreneurDIY way to digitize old photos. I would recommend you use a really HQ camera and spend a couple of hours getting these photos digitized. Google Photos is Legit if you haven't realized yet. For individual photos, I would recommend using one off services like Upwork or Fiverr.
