COLOR -THE BEGINING


JAMES ClERK MAXWELL- in 1861 photographing a scene  on three BLACK & WHITE film plates, using RED, GREEN, BLUEfilters respectively. He then made positive transparencies from negatives and illuminated them seperately in three lantern slide projectors, each fitted with either a  RED, a GREEN or a BLUE filter so that the projected images is superimposed on the viewing screen.
The combined images reproduced original color. This process is called ''ADDITIVE COLOR MIXING''.
