Quote: - scan at 600 dpi with a slightly rotated cover on the scanner. Why rotated? Just asking as someone who always fiddles to absolutely align the cover parallel to the scanner's edge. Just slabbing it on rotated and do this in "post production" ... have to ponder it. Has it any other positive side-effects?
It's more a feeling/experience that I get less Moiré this way, and as VirusPil said - it sometimes helps against shadow and reflecting effects. Also, I never get it absolutely parellel so trying to do that would cost me much more time than rotate it on purpose and correct it later. And - Photoshop has a great tool to do the correction. The cover is perfectly aligned after the rotation. BTW - if I scan at 1200 dpi I try to get it parallel too because my impression is that it has no effects on such a high resolution. The german "ct" had once an article about side effects on rotating raster images specialy in combination with scaling and they are not all bad, but I don't have it anymore and don't remember any details.
