[. . . ] The values of the image will be adjusted based on the selected point. The default level for the white point is 255 for each RGB channel. Click the black-point button. 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. Calibrate the image following the steps in white, black, and gray point corrections section. 54 ADVANCED IMAGE PROCESSING TONE-CURVE / HISTOGRAM AUTO SETTING Click the auto-setting button. The change is immediately reflected in the displayed image. The auto-setting function automatically adjusts the tone curve and histogram to maximize image data.

To view the change in the histogram, press the apply button. Click the reset button to cancel the auto setting. DISPLAYING THE COLOR HISTOGRAMS Click the color-histogram button to view the red, green, and blue histograms. Click the histogram RGB display button again to close the color histogram display. 55 HISTOGRAM CORRECTIONS The histogram indicates the distribution of pixels with specific brightness and color values of the displayed image.
