You have the get the lighting right, a special tripod to be perpendicular to camera, etc. You would end up spending some good money to get the appropriate lighting. The scanner will be slower(for the cheaper ones), but they will be consistent throughout the scan on light, without reflections or variations.
My wife and I have a number of photos we would like to digitize and archive. I read recently that a faster alternative to scanning is to use a good digital camera and tripod to actually photograph each photo. I'd appreciate any suggestions regarding a good camera for that purpose. I don't know if I would use a single reflex enough to justify the cost. Thank you.
