Tints are achieved by adding white, thereby increasing lightness Shades are achieved by adding black, thereby decreasing lightness Tones are achieved by adding gray, thereby decreasing colorfulness. Monochromatic color gradient on color wheelĪ monochromatic color scheme comprises ( tones, tints, and shades) of a single hue. This is sometimes required in cases where a color image would render in a confusing manner given the colors and patterns present in the source image and the selection filters used (typically red and its complement, cyan). The selection of weighting so provides a wide variety of artistic expression in the final monochrome image.įor production of an anaglyph image the original color stereogram source may first be reduced to monochrome in order to simplify the rendering of the image. If the red channel is eliminated and the green and blue combined then the effect will be similar to that of orthochromatic film or the use of a cyan filter on panchromatic film. The weighting of individual channels may be selected to achieve a desired artistic effect if only the red channel is selected by the weighting then the effect will be similar to that of using a red filter on panchromatic film. In digital photography, monochrome is the capture of only shades of black by the sensor, or by post-processing a color image to present only the perceived brightness by combining the values of multiple channels (usually red, blue, and green). Although color photography was possible even in the late 19th century, easily used color films, such as Kodachrome, were not available until the mid-1930s. Originally, all photography was done in monochrome. In film photography, monochrome is typically the use of black-and-white film.
