Joe D.with adjusting brightness and such to a scan -
with one major consideration.....
the end result should be an image closer to what the card or item looks like - - - not further away.
Basically - if the initial scan looks more like the card than the brightness adjusted scan.... then I would have a problem with the adjustment.
My home scanner is strange - if I scan more than one item at a time - the resulting scan is different (brightness contrast) than if I scan items individually.
I don't know why - I guess the scanner looks at the entire image area and tries to optimize things.
I don't bother adjusting my scans brightness / contrast - unless for some reason my scan looks noticeably different than the original.
imo -
now... some auction houses adjust the brightness / contrast to improve the overall look of the item (making it different looking than the original)
heck - I know of one auction house item that had obvious doctoring done to the scan. Flaws were lightened / image tone was changed / and some of the flaws seemed to disappear altogether.
It was either a very good doctor-job of a photo.... or harry potter did the scanning .
