I'm a new creative cloud photoshop CC user. How do you open the photoshop workspace.
Once you've installed the Photoshop CC application on your computer, and have installed the available updates via the Creative Cloud application, you start the application. It's just another application on your computer.
If you'll be so kind as to give just a bit more information about what kind of system you have, I'm sure someone will be able to provide a bit more specific information about just how to do that.
