Basic questions about scanners
Posted on 2001-06-16
Can someone tell me the crucial specs for determining the kind of quality I can get from a scanner? I need a scanner that will give reasonable quality scanning 3x5 and 4x6 35mm photo prints and slides (converting our snapshots).
I bought a cheapo with 300 x 600 dpi optical resolution and 4800 x 4800 dpi interpolated resolution. It is inadequate for getting decent resolution when set at 300 x 600 dpi. At higher resolutions it is excruciatingly slow and often crashes my computer and the images look about the same anyway.
I do not need extremely high quality, but would like faster operation and reasonable resolution (not grainy) images.
