Color Screen is a collection of tools for working with scans of additive screen processes of early color photography.
Additive color screen processes used panchromatic negative which was exposed through a color screen filter pretty much same was as today CCD and CMOS chips use Bayer filter. The negative was then copied to (black and white) transparency which yield to color picture when viewed through the viewing screen filter.
Our tool can bring back to life collection of negatives of such processes and reveal original color. In addition many of the positives now appears faded because the dyes used in manufacture of the viewing screens are not light stable. In such cases we can recover original color from the infrared scan of the slide which determines the original image recorded in the black and white transparency. With less precision one can also use RGB scans.
