Using the Sample Size button

The Sample Size button provides options for choosing how

extensively the color information will be read — whether the

color information will apply to a pixel, a 2-pixel by 2-pixel

area, or a wider expanse (maximum 5-pixel by 5-pixel area).

When you click on the Sample Size button, the drop-down

menu below appears:

Determines how the numbers in

the Color Meter Display are

shown — in absolute values or

in percentages

Value and Percent

• If you choose Value, the numbers in the Color Meter

Display represent the values in the 0-to-255 pixel scale. For

instance, an R value of 23 indicates that the sampling size

selected has a red color value of 23. Value is calculated by

multiplying the percentage by the constant 255 (value =

255 x percent).

• If you choose Percent, the numbers represent the percent-

age of the maximum intensity of the pixel. For instance, a

G value of 35% indicates that the sampling size selected

has a green color value to be 35 percent intense (out of 100

percent). Percent is calculated by dividing the constant 255

by the value (percent = 255 ÷ value).
