6. Photoshop Terminology File (Image document, formats: jpg, png, psd, gif) Workspace (Gray area to manage files) Option Bar (File, Image, View, Filter, Windows) Tool Bar (Different brushes, type, selection, color tools)

7. Options bar The tool options bar gives you instant access to different settings for the tool you're using. You can also customize any tool and save the customized version to use again.

8. Layers With layers, you can work on one element without disturbing others. To rearrange elements, simply shift the order in the Layers palette. You can lock layers to prevent accidental changes, hide them to get a clear view of the element you're working on, and link layers to move them as a group. The Layers palette also makes it easy to apply instant, editable effects including blending modes, adjustment layers, and layer effects.

9. History palette Undo or redo multiple steps with the History palette. Or store a snapshot--a temporary copy of the image--in the palette, and continue experimenting. If you don't like the results, simply return to the snapshot.

10. Customizable workspace Personalize your Photoshop desktop by arranging a layout of palettes and saving the arrangement as a workspace. Or create task-specific workspaces--one to provide easy access to painting tools, for example, and another for photo retouching.
