The Photo Persona is the default Persona that you'll probably spend most of your time in. It hosts a range of commonly used photo editing tools for easy access while editing.
The tools presented vertically down the left of the workspace are mostly unique to the Photo Persona. Some other areas of the workspace pertinent to this Persona are the Document Menu, Commands Menu and Studios.
The Document Menu is common to both the Photo Persona and Selections Persona. It hosts the same set of commands which are focused on document-level features such as document resize, print, export, flatten, and various design aids (snapping, grids and guides).
The Commands Menu differs between Personas—the list of commands are context sensitive to the currently active Persona, and support the Persona's way of working.
For Photo Persona, the commands available are focused on pasting or placing content on the page, as well as various operations that can be performed on layer content.
The set of Studios in this Persona is shared with the Selections Persona and offers layers, colour, adjustments, filters, channels and many more essential features. The Studios support the current Persona's toolset.
