LogEtronic Color Correction.

The LogEtronic Color Separator is designed to help one man make one set of color separation negatives in one hour. The Separator electronically accomplishes color correction masking, highlight masking and shadow masking - producing continuous tone separations, from either positive or negative transparencies, at enlarged or reduced scale. It is inherently simple, reliable, and flexible enough for use in trade shops where the typical case is the special case.
