Channel Mixer is available in the Color: Looks Pack.
Used to mix the color channels together. The red channel can have some of the blue channel introduced to it, for example. This can be useful for adjusting the color balance in a natural way, since the adjustments are based on another color channel from the source image.
The channel mixer is an effective option for creating a black and white image with extensive control over the contrast. Setting all values to zero, and then increasing the Red value in each color channel to 1.0, for example, will give you a black & white image of only the red channel. The same technique can be used with the green or blue channels as well.
Red
- Red: Sets the amount of the source red channel that is used to create the red output of your image. The default value of 1.0 delivers the red channel in its original state.
- Green: Sets the amount of the source green channel that is used to create the red output. This is set to 0.0 by default. Decreasing this value will darken the red output, based on the contrast contained in the green channel. Increasing the value will brighten the red output, based on the contrast of the green channel.
- Blue: Sets the amount of the source blue channel that is used to create the red output. This is set to 0.0 by default. Decreasing this value will darken the red output, based on the contrast contained in the blue channel. Increasing the value will brighten the red output, based on the contrast of the blue channel.
- Constant: Controls the base value of the red channel. This value is calculated after the three channels above are mixed, and increases or decreases the total output of the red channel, based on the sum of the three channels above.
Green
- Red: Sets the amount of the source red channel that is used to create the green output of your image. This is set to 0.0 by default. Decreasing this value will darken the green output, based on the contrast contained in the red channel. Increasing the value will brighten the green output, based on the contrast of the red channel.
- Green: Sets the amount of the source green channel that is used to create the green output of your image. The default value of 1.0 delivers the green channel in its original state.
- Blue: Sets the amount of the source blue channel that is used to create the green output. This is set to 0.0 by default. Decreasing this value will darken the green output, based on the contrast contained in the blue channel. Increasing the value will brighten the green output, based on the contrast of the blue channel.
- Constant: Controls the base value of the green channel. This value is calculated after the three channels above are mixed, and increases or decreases the total output of the red channel, based on the sum of the three channels above.
Blue
