Photoshop actions can be a real boon. For a lot of people (myself included) recording actions removes the tedium of repetitive tasks, saves time and boosts workflow. Recording actions can be as simple or as complex as you like, the only limit is your imagination and Photoshop skills.
Photoshop actions go beyond recording your own actions, you can also import ready made actions giving you a lot more time saving options and effects.
