Creating an Action (Sepia)
The New Action dialog closes and Photoshop is now recording our action. Notice in the Actions palette that our new action is highlighted and the record button is active.
We're now ready to perform the steps that go into our action.
The next step in the sepia process is adding a Hue/Saturation adjustment layer by clicking on the Create new fill or adjustment layer button in the Layers palette.
In the Hue/Saturation dialog box I set Hue to 15, Saturation to 25 and checked Colorize. After making these adjustments I clicked Ok.
