[. . . ] E INSTRUCTION MANUAL 9222-7300-11 HA-A205 2 BEFORE YOU BEGIN Before installing the DiMAGE Viewer software, read the data-transfer section in the camera manual. This section details how to connect the camera to a computer using the supplied USB cable.

[. . . ] With the RGB channel selected, click on the tone curve near the top and bottom to add two nodes. Slightly move the top node up and the bottom node down. This will increase the angle of the central portion of the tone curve and increase the contrast of the image without making an overall change in image brightness. By selecting individual color channels on the tone curve, adjustments to the overall color of an image can be made. This can be used to eliminate unnatural color casts or add warmth to a picture. If the image is too red, green, or blue, simply drag the corresponding color-channel curve down until the color appears natural. If the color cast is predominantly one of the secondary colors, cyan, magenta, or yellow, move the curve of the complementary color up. In this example, the image is too yellow. By moving the blue curve up, the image looks more neutral. For more on color, see page 38. 49 ADVANCED IMAGE PROCESSING White, black, and gray-point corrections Advanced image corrections can be made by specifying a white, black, and gray point within the image.
