Turn on the scanner, then your computer. 2 Install the SprintScan software, then restart your computer as instructed. [. . . ] The SprintScan software neutralizes the point by adjusting the brightness levels, then adjusts the values in the rest of the image accordingly. 3-10 Adjusting brightness, contrast, and midtone (gamma) As you use the controls to vary different components of an image, you'll see the results almost instantly in the preview window. To make changes to brightness, contrast, and midtone (gamma) values: · Choose Contrast/Brightness on the Image menu. The use of each of the controls in the Contrast/Brightness dialog box is described in the sections that follow. The Reset button undoes any changes you make and resets the sliders to their values as stored in the settings file. Brightness control Moving the Brightness slider increases or decreases the overall amount of light in the image. Output values increase as the slider moves toward the right. Use the Channel pop-up menu to alter values for all colors (RGB) or for individual color channels (Red, Green, Blue). (If you are scanning in grayscale, the only active choice in the menu is Black. ) Brightening a color makes it more apparent. Brightening green, for example, will make the entire image appear green, while dimming green will make the image appear more magenta (magenta is the complement of green). Advanced scanning settings 3-11 Contrast control Moving the Contrast slider alters the contrast between dark and light areas. High contrast, at the right end of the slider, makes everything look starkly black and white; low contrast makes everything look gray. As with the Brightness control, you can vary all color channels or individual channels using the Channel pop-up menu, if you are scanning in color. The tonescale curve is a graph of input values against output values. The gamma () value is an exponential value controlling the shape of the curve. When the curve has an upward bow in it, the midtones (middle range) of the output have been brightened compared with the input. This effect of brightening midtones is an approximation of how human eyes see images. A gamma value of 1 results in a straight line. As you move the Gamma slider to the right, the tonescale curve bows increasingly upward, indicating brightening of the the midtones. Use the Channel pop-up menu to choose all color channels or individual channels. With an individual color selected, moving the slider to the left has the effect of removing that color compared to the other two and heightening its complement. For example, if you choose the blue channel and move the gamma slider to the left, the image will appear more yellow. Gamma control 3-12 Adjusting the tonescale curve The Tonescale dialog box lets you change the highlights, midtones, and shadows of an image separately by adjusting the tonescale curve. To display the Tonescale dialog box: · Choose Tonescale from the Image menu. The lower left corner of the scale represents the darkest values, and the upper right corner is the lightest values. The horizontal axis represents input from the original, and the vertical axis the output. At the top is a pop-up menu from which you choose which channel components to modify: RGB reflects all color components taken together.
