When you click on one of the pickers in the Exposure tab, and then hover over an
image, the cursor changes to an eye dropper. If you look in the status bar, you will
see two R G B numbers changing as you move around the image. The two numbers
indicate the R G B values of the pixel under the cursor. The R G B values represent
the source pixel (unprocessed) and the current pixel as it appears on the screen.
