The top row contains zones 1, 3, 5, 7 and 9. Tonal values are compressed in the monitor display and print. (The tonal range is 5, rather than 8, zones.). The second row contains dark colors, the third contains pure primaries (R,Y,G,C,B,M), and the fourth contains pastels. HTML color names are shown in brackets [...]. In some cases they differ from conventional names. This chart is fairly simple to use. If you are metering off a surface that subjectively resembles one of the colors, make the exposure adjustment (relative zone 5) shown on the right. For example, if you are metering off a pure yellow surface, increase the exposure by 1½ f-stops above the meter reading (zone 5), i.e., place it at zone 6½. The values on the chart are accurate to about ±¼. Courtesy of Norman Koren Photography... Link above. |
