Photoshop actions are semi-automated or fully automated program sequences. In other words, an action contains predefined work steps that are executed one after the other when activated.
With fully automated actions, you start the action and the result is available immediately after the action has been completed. With semi-automated actions, the program sequence stops in between so that you can carry out manual work steps. You then continue with the action.
Where can I find the actions in Photoshop?
You can manage your Photoshop actions via the Actions panel, which you can access under Window>Actions. There you have the option of creating your own actions, importing actions from others and starting or customizing actions.
The advantages: work more effectively and apply effects from others to your own images
Especially if you apply a certain workflow multiple times to different images, you can save an enormous amount of time with the help of a Photoshop action. For example, if you want to apply a certain look or effect to an entire photo series.
Since Photoshop actions can be saved and imported in the form of ATN files and thus shared with others, you can also use other people's workflows for your work. On TutKit.com you'll find hundreds of Photoshop actions that you can use to edit your images in just a few clicks.
