With a single click of a button you can add multiple layers, transform your image, or do anything else you normally do within Photoshop.

For example, I've created an action that adds three separate sharpening layers and a text layer with my watermark. I use it to finish every portrait I edit.

To create an action, open the actions panel and press the record button. Work through the steps you want to turn into an action and when you're done press stop. To perform the action, select it from the list and press play.
