LazPaint: Scanner backlight compensation?
« on: September 14, 2014, 04:55:41 pm »
I have a diapositive/negative scanner. As it can be seen from the image attached (with no film in the scanner) backlight is not even on the whole surface.
Is there a filter in LazPaint, which could compensate backlight non-homogeneousness?

Yes, with two layers. If you put the backlight as a layer on top of the scanned document, and use divide blend mode, I suppose it could cancel the variations.
