Adjust the colour of individual channels to produce effects not easily achieved with other colour adjustment tools.
Settings
Apply this adjustment via the Adjustments panel using the following settings:
Colour space—selects the colour space (RGB, CMYK, etc.) for the output channel.
Channels—specifies a single colour channel for the previously chosen Colour space to apply the adjustment to, including the layer's alpha channel.
The sliders control the contribution of the named colour to the selected output channel. Drag the slider to the left to decrease the level of the named colour, drag the slider to the right to increase it.
Offset—controls the overall influence the selected output channel has on the image as a whole. Drag the slider to the left to decrease the output channel's contribution, drag the slider to the right to increase it.
Opacity—sets the level of visibility of the adjustment.
Merge—merges the current adjustment layer with the layer immediately below it in the layer order.
Reset—reverts all adjustment settings to default.
Delete—closes the settings and deletes the adjustment layer, removing the adjustment.
Add Preset—adds the current adjustment settings as a preset for use with later images and projects.
