Original Image Auto Level Adjusted DocuMate 510 Scanner Installation Guide 29 Scanning Items Adjusting Color Settings The buttons for manually adjusting a preview image's color settings offer several advanced color options. The availability of each option is dependent upon the selected Image Type for the image. Highlight/Shadow Levels Curves Color Balance Hue/Saturation/Lightness Color Drop-out Highlight/Shadow Levels Images have light and dark areas. The highlight is the lightest spot on an image; shadow is the darkest spot. The range of colors between the highlight and shadow determines the range of colors of the image. Using the Highlight/Shadow Levels features, however, you can extend the original range of colors between the highlight and shadow to reveal more details in the midrange colors. 30 DocuMate 510 Scanner Installation Guide Scanning Items To adjust the highlight and shadow levels: 1. The dialog box that opens shows a histogram of the saturation, gamma, and hue (S, G, H) of the range of colors for the highlight and shadow. Saturation is the strength or purity of a color, gamma controls the brightness of the midtones of the color, and hue is the color your eyes see as reflected from the image. The gamma setting in this dialog box is in conjunction with the hue and saturation but you can also set gamma by itself for an image. From the Channel drop-down list, choose RGB to adjust all the channels together, or choose a single channel if available. Enter new settings in the boxes for the three levels, or drag the small triangles at the bottom of the histogram. As you change the settings, the histogram changes to reflect the new levels. Click Preview to see the effect of the new settings on the preview image. Click OK when the levels are what you want. Curves Like the Highlight/Shadow levels, the Curves feature also adjusts the range of midtone colors on an image. However, with the Curves feature you can set the gamma individually to adjust midtone levels without losing details from the lightest or darkest areas. DocuMate 510 Scanner Installation Guide 31 Scanning Items To adjust the gamma curve: 1. The gamma of the original image is represented by a straight line from the lower left to upper right corners. Changing the straight line to a curve changes the gamma setting for the midtones on the original image. 2. From the Channel drop-down list, choose RGB to adjust the gamma of all the channels together, or choose a single channel if available. The input and output values represent values on the horizontal and vertical axes for the new gamma setting.
