Action Palette Basics
Photoshop CS6 Tutorial
How to Use the Photoshop Actions Panel
The actions palette is useful in automating tasks that you perform multiple times. For instance, you may have a batch of images you wish to scale and convert to black and white.
To create an action, you turn on the action's record function and perform the steps on image one. That action would then be applied to the remaining images in the batch
Open an image and choose New Action... from the Actions palette pull down menu.
Name the action in the dialog box and press the Record button.
Choose Image > Adjustments > Black and White, then press OK.
Choose Image > Image Size and set the size to 50 percent for Width and Height. Press OK.
Press the Stop Recording button on the Actions palette.
Your new action is now listed in the Actions palette.
Open a new image, select the new action you just created and press the Play button.
