Actions in Adobe Photoshop are sets of recorded steps that automate repetitive tasks. These collections of commands, saved with a specific file extension, enable users to apply complex effects or workflows consistently with a single click. For instance, a series of adjustments to enhance portrait photos can be recorded as an action and then applied to multiple images quickly.
Employing these automated processes can significantly increase efficiency and productivity for graphic designers and photographers. They allow for standardization of image editing processes across large projects and reduce the potential for human error. Historically, these capabilities have evolved from simple batch processing techniques to sophisticated scripting and automation tools within the software, becoming a cornerstone of professional digital imaging workflows.
