Learning how to select areas of an image is of primary importance— you must first select what you want to affect. Once you've made a selection, only the area within the selection can be edited. Areas outside the selection are protected from change.

In this lesson, you'll learn how to do the following:

• Select parts of an image using a variety of tools.

• Reposition a selection marquee.

• Deselect a selection.

• Move and duplicate a selection.

• Constrain the movement of a selection.

• Choose areas of an image based on proximity or color of pixels.

• Adjust a selection with the arrow keys.

• Add to and subtract from selections.

• Use multiple selection tools to make a complex selection.

• Erase within a selection.

This lesson will take about 30 minutes to complete. The lesson is designed to be done in Adobe Photoshop, but information on using similar functionality in Adobe ImageReady is included where appropriate.

If needed, remove the previous lesson folder from your hard drive, and copy the Lesson04 folder onto it. As you work on this lesson, you'll overwrite the start files. If you need to restore the start files, copy them from the Adobe Photoshop 7.0 Classroom in a Book CD.

Note: Windows users need to unlock the lesson files before using them. For more information, see "Copying the Classroom in a Book files" on page 4.
