In-Depth Information
The Default Lasso tool ( ) allows you to click and draw, just like a brush, to make a selection. When us-
ing this tool, you typically need to encompass the entire area that you want to select, starting and stop-
ping at the same spot to create a closed selection.
Polygonal Lasso tool
Using the Polygonal Lasso tool ( ), you can click and release to create straight lines from one point to
another. Use this tool to quickly make straight line selections. Using the Polygon Lasso tool is fast and
easy; however, in Lesson 4, “The Pen Tool: Beyond the Primer”, you will discover how to use the pre-
ferred method for making straight line selections, which is the Pen tool.
Magnetic Lasso tool
The Magnetic Lasso tool ( ) allows you select a location on the edge of an object that you want to select.
As you move your cursor along the object, the selection border snaps to the edges of the object in the im-
age. Based on a few settings from you, Photoshop automatically adds points that create a selection when
you close the selection process.
Alternating between the Polygonal and regular Lasso tool
You can easily switch between the Lasso tool and the Polygonal lasso tool, even if you are already in the
middle of creating a selection. In this next section, you have an opportunity to mix a straight line polygon
Lasso selection with a selection made with the more freeform Lasso tool.
