The resolution, the amount of detail captured in the original cannot be easily improved upon and in fact it can only be guessed at. There are 2 ways to copy a print, the first being a good flatbed scanner, the second being a copy station created by placing 2 lights opposite each other, the lights being placed at a 45 degree angle to the object being copied, and opposite each other. The camera is best affixed to a bracket with a lense usually in the 50-85mm focal length, set an aperature usually f5.6-f8.0 to deliver the best optical performance possible. If a piece of glass is placed over the photo to be copied it must be "non-glare"...All of this is more work and not significantly better than a flatbed scanner but does have the advantage of being a setup capable of copying 3 dimensional items.
I use either a Canon F1 film camera with a 50mm macro lense or a Canon t4i digital camera with a 100mm macro lense - fixed focal length lenses delivering better optical quality than zoom lenses.
