[. . . ] This instruction manual does not provide instruction in the basic operation of the personal computers, or the basic operation of Windows or Macintosh operating systems; refer to the manuals supplied with the computer. The examples in this manual use Windows software. The appearance of the screens may differ from the examples when using Macintosh or other Windows operating systems. Every precaution has been taken to ensure the accuracy of this material. [. . . ] If the color cast is predominantly one of the secondary colors, cyan, magenta, or yellow, move the curve of the complementary color up. For example, if the image is too yellow, move the blue curve up. For more on color, see page 35. 51 WHITE, BLACK, AND GRAY-POINT CORRECTIONS 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 immediately reflected in the displayed image. Click the white-point button; the mouse pointer changes to the white dropper tool. With the dropper tool, click on the brightest neutral area of the image to define it as the white point. 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. The gamma slider defines the mid-tones of the image. Dragging the gamma slider to the right will darken the image, and dragging it to the left will brighten it. Similar to the tone-curve correction described on page 50, the gamma slider allows the brightness of the image to be adjusted without loosing image information. The input highlight slider sets the white level. As the slider is moved to the left, an apparent increase in contrast can be seen in the displayed image. All pixels to the right of the slider are set to 255 and any image detail they may contain will be lost. This can be an important tool for improving copy images of text on a white background. Uneven illumination, or faded or stained paper can be distracting when copying text or line art. By adjusting the white level, the imperfections of the white background can be eliminated leaving only the darker text visible. The input shadow slider sets the black level. As the slider is moved to the right, an apparent increase in contrast can be seen in the displayed image.
