Although you can apply more than one image adjustment to the same masked area, you might want to add a different adjustment to exactly the same area of the image and retain separate control over each mask on different layers. This can be done by copying a mask to another Layer.
Copying masks is possible between the adjustments Layers only.
Note that the function will overwrite an existing mask without warning, so if you have a lot of Layers, double-check that you are copying to the correct layer first.
- Go to the Layers tool.
- Create a new Layer or select an existing Layer you want the mask to be copied to.
- Right-click on that layer and select Copy Mask From -> Layer No. (e.g., Layer 1). The mask will be copied and applied to another layer (e.g., Layer 2).
- The copied mask can now be adjusted further and you can apply the desired image adjustments.
Note that you can copy a Linear Gradient Mask (L) or Radial Gradient Mask (T) to another Layer and still retain the possibilities to readjust the mask on the new layer. This can provide a powerful workflow if you just need to tweak the coverage of the mask slightly on that new layer.
