Selection Tools > Lasso Tools

The lasso tools allow you to select precise areas of an image by drawing or tracing the selection outline. There are three lasso tools available:

Lasso Tools
1.Lasso Tool (L)
This is a freehand selection tool. Click and hold your left mouse button on the image and draw your selection.

2.Polygonal Lasso Tool (Shift + L)
Similar to the lasso tool, except that instead of holding your mouse button down to draw, left-click on various points to create a selection with a series of straight edges.

You can also hold down the Alt key to draw freehand sections.

3.Magnetic Lasso Tool (Shift + L)

This is a very handy tool for selecting areas which have reasonably well-defined edges. Left-click at the starting point of your selection and simply moves the mouse along the edge.

"Fastening points" are automatically made at various points along the edges. Left-click at any time to add a fastening point manually.
