Using Shapes

What You'll Do

In this lesson, you'll make selections using a marquee tool and a lasso tool, position a selection with the Move Tool, deselect a selection, and drag a complex selection into another image.

Selecting by Shape

The Photoshop selection tools make it easy to select objects that are rectangular or elliptical in nature. It would be a boring world if every image we wanted fell into one of those categories so fortunately, they don't. While some objects are round or square, most are unusual in shape. Making selections can sometimes be a painstaking process because many objects don't have clearly defined edges. To select an object by shape, you need to click the appropriate tool on the toolbox, then drag the pointer around the object. The selected area is defined by a marquee, or series of dotted lines, as shown in Figure 1.

Creating a Selection

Drawing a rectangular marquee is easier than drawing an elliptical marquee, but with practice, you'll be able to create both types of marquees easily. Table 1 lists the tools you can use to make selections using shapes. Figure 2 shows a marquee surrounding an irregular shape.

QUICKTIP

A marquee is sometimes referred to as marching ants because the dots within the marquee appear to be moving.

Using Fastening Points

Each time you click one of the marquee tools, a fastening point is added to the image. A fastening point is an anchor within the marquee. When the marquee pointer reaches the initial fastening point (after making its way around the image), a very small circle appears on the pointer, indicating that you have reached the starting point. Clicking the pointer when this circle appears closes the marquee. Some fastening points, such as those in a circular marquee, are not visible, while others, such as those created by the Polygonal or Magnetic Lasso Tools, are visible.
