ADVANCED IMAGE PROCESSING
On the tone-curve / histogram palette, corrections can be
made by specifying a white, black, and gray point within the
image. Locating an appropriate neutral area within the
image is critical to correctly calibrate the software. When the
dropper tool is selected, the RGB display is active and can
be used to evaluate the image area. All changes are imme-
diately reflected in the displayed image.
