Hi Jez, As large as you can is good advice for the scanning, but you'll struggle to get decent quality enlarging the print to a much bigger size than the original. 'Decent quality ' is in the eye of the beholder, it depends on the result needed and the audience's viewing distance. Kind regards, Dave. Sent from my BlackBerry 10 smartphone.

I have a number of photographs, 6 x 4 and 7 x 5 (and a couple of larger ones) that I have been lent as part of a project I'm doing. I'm scanning them all and I want to use to some of the scanned images for a public exhibition. I'm thinking the sizes for the exhibition will be a mix of A4/3/2/1 and maybe A0. Could anyone one advise at what DPI I need to scan these at please? I'm reading a lot of different advice from 600 dpi will be sufficient to 'scan as large as you can'. I have access to a Plustek OpticPro A320L scanner so it's a relatively good scanner. Any help would be most appreciated. Thanks in advance.
