Guest · Posted: Tue Oct 11, 2005 7:25 am Post subject: Deep Yellow Paper WAY Too Dark

Hello.

I am scanning with a Canon DR-9080c sheetfed scanner. Although some
of the pages of the documents are on white paper, other pages are on
colored paper (including a dark yellow), and the scanned image appears
very dark on the screen.

Is there a setting that I can change to "lighten up" the BACKGROUND
without making the TEXT any lighter? (In fact, some of the documents
are duplicated receipts and the text *needs* to be darker.)

Any help would be greatly appreciated.

Thanks,
Jessi

Gamma?

Or curves in general, if you want the text to become *darker* than it
was originally?

Also, just try "auto levels" (i.e. per-channel normalization) in any
graphics program, if the scan has *no* white parts (only yellow and black).
That way, the background should become white.
