With the dropper tool, click on the darkest neutral area of the image to define it as the black point. The values of the image will be adjusted based on the selected point. The default level for the black point is 0 for each RGB channel. 52 ADVANCED IMAGE PROCESSING Click the gray-point button. The grey point controls the color of the image. With the dropper tool, click a neutral area of the image to be defined as the gray point. The area used to calibrate the gray point must be neutral. The brightness level of the area is not important, but if the area has a definite color, the image will not be color balanced correctly. Click and hold the apply button to show the change on the histogram. Click the reset button to cancel all corrections. 53 SETTING THE WHITE AND BLACK-POINT VALUES The white and black-point values are set to 255 and 0 for each RGB level. Changing these values allow the calibration of an image with no true white or black. This is an advanced image-processing tool. Double-click on either the white-point or black-point button to activate the point-value-setting dialog box. Input the new white-point or black-point values. With the point-value-setting dialog box open, the mouse pointer can be used to measure the color of any point on the displayed image. Press the shift key (Windows) or command key (Macintosh) to display the CMY levels in the RGB display. The RGB display shows the original values for the image on the left and the current values for the image on the right.
