q Add Watch Point Button

By clicking on this button, you can add up to four watch points to your image. When you click on this button, the mouse cursor will change to a crosshair and enable you to place a watch point directly on the image. A watch point icon will be placed on the image displaying where you placed a watch point and an entry will be added to the “Watch Points” section that continually monitors the colors of the selected pixel or area.

You can move and reposition any of the watch points by clicking and dragging that point using the direct select tool. You can delete a watch point by clicking on the Delete Watch Point button next to that watch point.

w Color Model

This pull-down menu enables you to select the color model used to describe the colors within the “Watch Point” section. You can choose between RGB (red, green, and blue) and HSB (hue, saturation, and brightness) color models.

e Sample Size

Use this option to change the number of pixels which are used in sampling for both the current color under the mouse cursor as well as for each of the watch points. The default value for this option can be selected within the “Levels & Sampling” section of the “Preferences” dialog, or you can override the default and select from one of the following available options:

Point Sample

The Point Sample option samples only a single pixel. This is helpful if you want to be very precise when selecting a color and are able to target a pixel of a specific color.

3 x 3 Average

The 3 x 3 Average option samples a total of nine pixels in a grid of three pixels by three pixels and averages the colors of each pixel before displaying the result. Since areas within a photograph are generally made up of small variations of color, selecting this option provides a more accurate rendition of the color of the targeted area.

5 x 5 Average

The 5 x 5 Average option samples a total of twenty-five pixels in a grid of five pixels by five pixels and averages the colors of each pixel before displaying the result. This option is recommended for higher resolution images.
