I’m scanning dias with an Epson Perfection 2400 Photo (by the integrated TPU in the cover) but the result is
discouraging – images look blue and dark, faces are black, the snow is violet… I can correct this by some work with Photoshop (mostly by lowering the blue channel) but I wonder if the result will compare to the ouput of my analog
projector of dias
I thought that when the scanner "calibrates" this would mean it took into account some light and color parameters to give the best result but it seems not to be so… (I even thought it depends on the internal light that looks somewhat
blue/violet… is it possible?)
Do you think I’ll be forced to correct anyway with Photoshop or perhaps it is possible to correct it at scanner’s level by some sw utility, say some Epson profile?
Has someone already had this problem?
thanks for suggestions

Does your scanner have a re-calibrate option? Otherwise it may be a driver problem or worst case a hardware problem.

Try the following first:
Complete a pre-scan, then draw a marquee around the ara to be scanned. Do not include any of the border as this will upset the auto exposure option.
Click on the Auto button that will automatically remap the black and white points.
I would always use this process or similar when scanning transparent media.
Have you tried an autolevels in PhotoShop? If so then try the above.
