All pixels to the left of the slider are set to 0 and any image detail they may contain will be lost. The black and white output levels can be adjusted. By moving the output highlight and shadow sliders, the contrast of the image can be reduced. Click the color-histogram button to view the red, green, and blue histograms.
DIMAGE SCAN DUAL III UTILITY – IMAGE PROCESSING White, gray, and black 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 display image.
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. Double-click on either the white-point or black-point button to activate the point-value-setting dialog box. Enter the new white-point or black-point values. Click OK. 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.
DIMAGE SCAN DUAL III UTILITY – IMAGE PROCESSING Unsharp mask The unsharp mask sharpens edges in the image without affecting overall image contrast. This mask can be used with soft or slightly out-of-focus images. The effect of the unsharp mask is very subtle, but makes a significant improvement to the overall appearance of the image. Click the unsharp-mask button to open the unsharpmask dialog box. Drag the sliders or enter values in the text boxes to adjust the parameters of the mask.
Hue, saturation, and lightness palette This palette adjusts the image in reference to the HSB color model. These controls can be used to manipulate the color image rather than producing a realistic representation. The HSB color model defines color based upon human perception rather than photographic processes. Hue refers to each separate color in the model. Saturation is how S vivid each colors is. Lightness describes how bright or dark a color is in the color space.
JOB FILE LISTS Jobs can be used to make scan settings based on the final use of the image. See making-thefinal-scan using Job section in page 42.

AN INTRODUCTION TO COLOR Primary (RGB) and secondary (CMY) colors The RGB color model is an additive process that uses the primary colors of light: red, green, and blue. An additive color system mixes the three colors to recreate the entire spectrum of light. If all three colors are mixed, white light is produced. Television sets and computer monitors use RGB to create images. The CMY color model is a subtractive process that uses the secondary colors: cyan, magenta, and yellow.
COLOR EXAMPLES Complementary colors (p. 90) HSB color model (p. 81) Saturation GREEN YELLOW Lightness RED CYAN Hue BLUE MAGENTA Hue corrections Changes in hue rotate the original color values though a color space and reassigns a new hue based on the new position in that space. In this example, the original image was rotated 180°. For more on the hue, saturation, and brightness palette, see page 81.
