Adjusting Saturation and Color BalanceYou can brighten colors that have faded with time or due to colorcast by using (Saturation/Color Balance) in ScanGear (scanner driver)'s Advanced Mode tab. Note
Move (Slider) under Color Balance to the left or right to emphasize the corresponding color. Cyan & Red Magenta & Green Yellow & Blue These are complementary color pairs (each pair produces a shade of gray when mixed). You can reproduce the natural colors of the scene by reducing the cast color and increasing the complementary color. It is usually difficult to correct the image completely by adjusting only one color pair. It is recommended that you find a portion in the image where it should be white, and adjust all three color pairs so that the portion turns white. You can also enter a value (-127 to 127). Below is an example of an image in which the "Cyan & Red" pair has been adjusted.Cyan is increasedRed is increased 783
