Chapter 2. Photoshop Essentials > Editing and Organizing Images

Editing and Organizing Images

In this section, we'll work on the essentials of Photoshop—the ability to organize artwork into layers, to select parts of an image for editing, to use silhouettes and masks, and to add and format text. This will build a foundation for later work. Basic ads and posters (good ones, too) can be created using just these tools.

About Bitmap Art

To understand how Photoshop works, it's helpful to know how bitmap art is put together. When an image is referred to as a bitmap (or “raster”), it simply means that it's made up of lots of tiny squares of color called pixels. Pixels are generally so small that they are not individually visible in a final, published image. Combinations of pixels are perceived as a continuous tone rather than a grid of squares.
