Anotations

Scope note:

Photographic processes that produce an additive color image using a screen of minute red, green, and blue filters to record the relative intensity of each hue on a panchromatic, black-and-white emulsion which is processed to form a transparency. When viewed through a similar filter, each filter contributes its hue with its intensity modulated by the silver image.
