Most professional printing (glossy magazines etc.) are printed at 300 DPI, which translates to roughly 0.08 mm per dot. I think high quality digital printing also uses this resolution. If you want sharp A4-size pictures, I'd go for at least 3 MP, preferably 4. In any case, you haven't yet said anything about your budget... I think more information in that direction would help a lot. -- Alex Shnitman <[EMAIL PROTECTED]> http://www.hectic.net/ UIN 188956 PGP 0xEC5D619D / E1 F2 7B 6C A0 31 80 28 63 B8 02 BA 65 C7 8B BA ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
