Identifying Which Selection Tools to Use

As you edit images for print design, you are often faced with various selection tasks—everything from selecting an entire background to selecting a small part of a much larger image. Some selections are easier to make than others. Therefore, Photoshop has provided us with several tools for making selections. The first step toward making all of your selections quickly and easily is choosing the best tool for the task at hand. In order to identify which selection tool is best for handling these various selection tasks, you must learn how each one of them works. Let’s dig into our toolbox and take a close look at how each one of these tools can be used to make our image-editing lives a whole lot easier.

To make a selection with the Rectangular Marquee tool, check the Options palette at the top of the screen and make sure the Feather amount is set to 0px and Style is set to Normal. Making a selection with a feathered value any higher than 0px adds a soft edge to the selection. Then all you have to do is click and drag.

The Elliptical Marquee
You can access the Elliptical Marquee tool by clicking and holding the currently visible Marquee tool icon in the Tools palette and selecting Elliptical Marquee Tool from the pop-up menu that appears. You can also toggle between the Rectangular and Elliptical Marquee tools by pressing Shift+M. To make a selection with the Elliptical Marquee tool, check the Options palette at the top of the screen and make sure Anti-alias is enabled, the Feather amount is set to 0px, and Style is set to Normal. Then click and drag to make an elliptical selection.

The Single Row and Single Column Marquee Tools
These two selection tools are hidden away under the Rectangular and Elliptical Marquee tools in the Tools palette. You access them by holding down the currently visible Marquee tool icon in the Tools palette and selecting them from the pop-up menu that appears. Note that you cannot access them by using the Shift+M keyboard shortcut. These tools are limited in that they allow you to select only a 1-pixel-wide row or column. They can be useful for cleaning up the edges of geometric-shaped image layers. For example, let’s suppose you’ve selected an image of a door and cut and pasted it to its own layer. Then let’s say you’ve deleted or changed the background layer. After doing so, you notice that there are some different-colored pixels along the edges of the door, indicating that your initial selection before cutting the image was not accurate. To clean this up, use the Single Row or Single Column Marquee tool to select the pixels and delete them from the layer.

What Is Anti-aliasing?
The Anti-alias option applies a slight transition between pixels, resulting in a smooth selection rather than a jagged one.
