Applying a Color Grade as You Clone

You can apply a color grade to your source image as you paint. You can apply the color grade to any clone operation, whether from an external image or from a channel's surface. You can:

• Change the color values in the source image, either all at once, or by RGB channel.

• Alter the Contrast or Saturation.

• Use the value curve to apply a specific change to the colors. Mari grades the colors by converting the input value (on the x axis) to the matching value on the y axis.

For example:

Setting	Result
Default settings
Blue component turned down:
Colors at default settings, but Contrast turned down:
All colors and Contrast at default values, but the following value curve applied:
