To close a selection area, click the first point in the selection.The Magnetic Lasso tool snaps to high-contrast edges. You can use the Options bar to control the way Photoshop detects edges: %u2022 Width is the distance from the edge where the cursor can be and still detect edges; set this higher to move the cursor farther from edges. %u2022 Contrast is how different the foreground can be from the background and be detected; you can set this value higher if there is a sharp difference between the foreground and background. %u2022 Frequency is the number of points that will be created to make the selection; setting this number higher creates finer selections, while setting it lower creates smoother edges.Polygonal Lasso tool cursorMagnetic Lasso tool cursorDrag near the edges of the object and the selection snaps to the edges.Click each spot to anchor the selection line.
