Hi, Jane,
I wanted to copy some old photos, too, and put them into one of those books you can get printed up online as gifts one year.
I scanned some but then quickly realized how time consuming it was, and I'd have to do some photo restoration-type work to get rid of the dust, the other issues, like the torn parts or folded lines in some of the photos, using PhotoShop. That quickly became tedious. I cleaned the scanner, I used canned air on the photos, but no luck at getting rid of what looked like dust.
I decided to then use my Nikon SLR camera or my Sony Cyber-shot camera, and a light box I made, and took a photo of the photos I wanted to use. I had the cameras set on the best setting possible, and from there, the photos I downloaded didn't have all that much to clean up and the resolution looked really good!
Here are a couple of photos of photos of my dad--done with the Sony Cyber-shot. One clearly shows 1937 on it, and the other, as near as I can tell, is from about 1924. You can see the white edge of the original photo in the 1924 picture, and a "spot" that I would have removed with PS, but I ended up not using the picture. In the 1937 photo, you can see the white edge at the top of the photo has some discoloration. When I uploaded this photo to the book-in-progress, I just cropped it out.
Hope your photos come out great, however you do them!
Smiles,
Sooz
