The A-Z of Photoshop User Interface
Photoshop user interface is simply what you get to see when you first launch the application. But that doesn’t say much about it. Understanding its Tabbed Window Interface or where all the Panels, Menus, Tools, and Functions are located is absolutely critical for a power user. Before you make any serious consideration about learning Photoshop you should be very comfortable with its user interface. Without a clear understanding of how they are organized and how they can be reorganized, you may never know how productive you could be with a very customized interface or knowing exactly where the tools and functions are located.
