Resolution is one of the main settings you may wish to look at- if you just want to "duplicate" the original size then 300 dpi is sufficient- more will just increase the size of the file without image improvement. If you want to enlarge the original photo that you scanned you have to go with a higher scanning resolution- for instance, if the original is 3"x5" and you would like to print it at double the size (6"x10"), then you need to scan it at 600 dpi. Unfortunately, there are some limitations when trying to enlarge a scanned photo as opposed to negatives or slides- it has a lesser dynamic range and resolution so this will eventually show up as you try increasing the magnification ratio.

Andrei, my scanner (agfa snapscan)is set default at 150 dpi and that represents the original size of the photo, but if i change that (to double size) the scans begin to "lose focus", also, i was told about an agfa software that corrects focus even at a 10%, do you know something about it ?

> Sorry, but I'm not an expert with Agfa scanners, at any rate, 150 dpi is not enough to duplicate a photo, let alone magnify it. It is sufficient if you want to post this on a web page or email but that's just about it.To my knowledge, Agfa has sort of lost interest in consumer scanners and the last models they sold were just labelled with their logo. If the photo(s) you want to digitize are just a one time deal, a photo lab could probably be a better choice- on the other hand, if you wish to have this sort of capability "in house", Epson offers a wide range of document scanners- before comiting though to a purchase, I would seriously consider whether you want to scan photos or negatives/slides- the latter is the way to go if you want to digitize and get a high quality output from your 35mm (or larger) films.
