LIGHT METERS AND “EIGHTEEN-PERCENT GRAY” In talking to photographers, you often hear the phrase 18 percent gray. This is the kind of gray that a Kodak gray card gives, as well as the tonality you get if you follow the indications on your camera’s light meter when you expose a pure white wall. It means that 18 percent of the light striking an object is reflected. Eighteen-percent gray is roughly the tonality you get when you mix equal amounts of white paint and black paint. ” Such a light meter does not “see” a white wall or puffy clouds or a bride’s white wedding gown; it “sees” these objects as gray.

The tonality extremes such as the highlights and shadow areas were also placed on the curving sections of the toe and the shoulder. As this photograph demonstrates, exposure is critical to good photography. When an image is overexposed, the gray tones of the scene are shifted to the toe portions of the curve and become darker, whereas the highlights fall on the upper portion of the straight line of the curve. 14 were printed normally, the highlights would be washed out and the shadows would be very dark.

This type of film is known as chromogenic film for its ability to generate colors from the latent silver halide image. This kind of spectral sensitivity filtration, together with dye coupling and eventual bleaching, is the basis for all color negative films, slide films, and color prints. Not all films generate color through dye coupling, however. Kodachrome’s color is introduced during film development rather than being present in the emulsion itself. , long lasting) than regular film. No matter what kind of film is used, photography is still about the capture and control of light as it falls on a scene or subject.
