Channel MixerThe Channel Mixer effect modifies a color channel using a mix of the current color channels. Use it to make creative color adjustments not easily done with the other color adjustment tools: Create high-quality grayscale images by choosing the percentage contribution from each color channel, create high-quality sepia-tone or other tinted images, and swap or duplicate channels. The Constant (-Const) controls specify the base amount of the input channel to be added to the output channel. Monochrome applies the same settings to all the output channels, creating a color image that contains only gray values. This is useful for images that you plan to convert to grayscale. If you select and then deselect Monochrome, you can modify the blend of each channel separately, creating a hand-tinted appearance. ![]() Original (left), with background layer's Green and Blue values decreased (center), and with background layer's Red-Blue values increased and Blue-Red values decreased (right) |
