Color Sampler Tool

The Color Sampler tool is the Eyedropper tool on steroids. Using the Color Sampler tool allows you to measure and continuously and interactively monitor, as you make your corrections, up to four separate locations in an image. Clicking an image area with the Color Sampler places a sequentially numbered Color Sampler point location and creates a measurement reading at the bottom of the info palette. The Info palette will show both before and after readings. When used with adjustment layers, you have the advantage of continuously updating, monitored, nondestructive editing.

Color Sampler points can be quickly and easily placed and moved using your Shift key while you are working in a Levels, Curves, or other adjustment layer dialog. To help me easily keep track of which Color Sampler points are which, I routinely set my color sampler points sequentially in tonal order as follows : #1 Highlight, #2 Quartertone, #3 Midtone, #4 3⁄4 tone/shadow. I set my neutral points first and then other key points such as skin tone areas. Using this tonal sequence to set my Color Sampler points provides me with easy-to-remember points from one image to another.
