Tool box

This is a quick summary of Photoshop CS3 Tools palette with a description of each tool’s functions and shortcuts. I decided to start at the beginning. The keyboard shortcut is in ( ).

The Photoshop Document

Photoshop’s “out of the box” workspace consists of the following components



Menu bar

You will probably already be familiar with the menu bar from other programs. This runs across the top of your Photoshop window, and contains various menu options for Photoshop’s tools.

Options bar

The options bar sits beneath the menu bar and holds contextualized options for different tools. It also contains the palette well, where you can “dock” palettes.

Tool Box

By default, the toolbox sits to the left of your Photoshop window, and contains shortcuts to Photoshop tools.

Palettes

Individual “panes” that hold information or options for working with your file, known as palettes, float on the right-hand side. Each palette is labeled with a tab, and can be minimized, closed, grouped with other palettes, or dragged to the palette well. In the example at the top of the next page, the Navigator palette contains a thumbnail of the image that allows you to zoom in or out of the image quickly, and to change the part of the image displayed on the screen.

Getting Started With Photoshop

In this introductory chapter, I’ll cover some of the basic tools and tasks that we’ll draw on in the later chapters. I’ll also share some of the shortcuts and time-savers that I use frequently. This chapter won’t give you an exhaustive review of the many things that Photoshop can do (where would it end!), but it should provide the bare bones that will help get beginners started. If you’re already familiar with the interface and can perform tasks like making selections, applying gradients, and working with layers, you might be want to skip ahead to the next chapter.
