Suppose you need to restrict a certain adjustment to 3 of 5 underlying layers (fig. 1).
- Create an adjustment layer, for instance, "Levels".
- Open the "Layers" dialog and select the adjusting ("Levels 1") and adjusted layers (in our example, "Layer 1", "Pattern Fill 1", and "Shape 1".
- Apply the "New Group from Selected'
command.
Although the selected layers are concealed deep inside the "Group 1" now, the image seems to be absolutely the same.
- In the Layers palette, pull the blending menu and choose the "Normal" mode* (fig. 2).
*The default blending mode for layer groups is "Pass Through". - Now the adjustment layer only affects the layers inside the group. (fig. 3).
