The marquee tool is certainly cool and when you
use the SHIFT and ALT keys to add or subtract from the selection, you can create some
pretty complex selections. However, often times, a free form
selection tool is what you really want. A freeform tool like the Lasso, allows
you to draw out a selection area much like you were tracing over an image through tracing
paper. [IMAGE]
To create a free form selection, simply choose the lasso tool [IMAGE]
and click and drag on the canvas. The selection will follow your drag.
Obviously, it is unlikely that you will succeed in making
a free form selection right the first time since it is very easy for your mouse
to slip. Fortunately, you can use the SHIFT and ALT keys to add or subtract
from a selection as well as use the ALT key down while you drag with the lasso to
create polygons much like you would do to create lines using one of the
paint tools as discussed yesterday.
Note that if you do not perfectly align up the beginning and the ending of a lasso selection, Photoshop will complete it for you by
drawing a line from the end to the beginning as the crow flies.
