Rumour has it that, if you scan a slide a few times out of register (ie taking the slide out of the holder each time and replacing it) and combine the scans in Photoshop you can effectively increase the resolution of the resultant scan (eg, 4 scans combined would effectively double the resolution to 4800 dpi).
Has anyone tried it? Any advice to offer?
I'm trying to get a better result than I do with a simple scan (see below) which is ok, but not brilliant.
