Scanning card images

[steve B]

There are so many different settings, both on scanning/photographing and especially on the display end that it's very common for an image to display differently on one device than another.

My scanner will automatically adjust the brightness depending on the image. So If I have say three dark cards and one lighter card I can see a difference when I move the active scanning area from one to the other.
(I can select an area that's just bigger than card size, scan, then move that selected area to the next card. I'm not sure other scanners will do that. )

If your monitor setting is bright or dim it will probably make a difference in how you perceive the colors.
