tool and is used to draw
freehand selection.

that you want to select and release
your mouse pointer, this will create
a starting point or anchor point.

19. 3. Magnetic Lasso Tool
-It is also known as an edge
detection tool. This tool is more
automated as compared to the
default lasso and polygonal lasso
tool. It automatically detects the
edge of the area or object that you
want to select as you move around it,
then snaps the selection outline to
the edge and holds it like a magnet.

AND SELECTS THE EDGES, SO YOU DON’T HAVE TO TRACE THEM MANUALLY.

clicking on its icon in the Tools palette.

color a pixel can be from the area we clicked on for it to be
included in the selection.

separated from the area you clicked on by pixels that fall outside the
Tolerance range will not be included in the selection.
