Can you recommend the best photo scanner to buy? I have a lot of photos to scan and store digitally. What features should I look for to ensure high-quality images? Thanks a lot for your help!
There are two basic divisions that determine the answer, and your post does not address either, so we need some additional information. Depending on the answers to those two, there may be an important third division.
(1) Are you trying to scan photographic film (negatives, slides, that sort of thing) or only photo prints (the final images on a paper-like material)? Generally, if you have the film, you can get better results by scanning it instead of the prints, but the equipment required is more specialized.
(2) How many scans are you trying to make, and how much time are you willing to spend on scanning? If by "a lot" you mean 200, and you just want to finish scanning in the next six months, then the answer will differ greatly from if you mean 20,000, and you want to finish in six weeks.
(3) The size of what you want to scan can make a major difference. If you want to scan film, but the only film you want to scan is 35mm, then there are far more choices at lower prices than if you want to scan larger film and/or oddball sizes. If you want to scan prints, if any are larger than 8.5x11.7", then your options will be far fewer and more expensive.
Last but not least, have you considered using a service? I haven't followed that market, but at one time, services like ScanCafe were a good choice for many people.
