With this process, additive color images are created using a screen of red, green, or 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. ]]></note></mads>
