When we use the
Quick Selection Tool
on an object like the pig statue in
Figure 78
, it does
not grab the entire pig with one stroke like it did with the flower in
Figure 44
.
The
Quick Selection Tool
is looking for edges. In the case of the flower, the edges were
well defined and easy to identify against the background. In
Figure 78
, the pig has a lot of
contours and three dimensional variations that make the edges more difficult to identify.
We also have shadows and a nearby planter to contend with.
To get a good selection, we need to make multiple passes along the body of the pig
Figure
78
(
1
) and then zoom in, so that we can see how well we did. Typically, as you move
around the outer edges while zoomed in, you will notice that the selection needs modifica-
tion (
2
). There are two selection tools on the
Options Bar
that allow you to add and sub-
tract from your original selection. They are shown in
panels 3 and 4
of
Figure 78
. The
Quick Selection Tool
is actually a
Brush Tool
. Just brush along the edges with these tools
to make your modifications.
We will now make the same selection with the
Lasso Selection Tool
.
Rather than having Photoshop search for the edges, we identify their rough location by
drawing a Lasso around the object as shown in
panel 1
of
Figure 79
.
With the
Lasso Tool
, you must complete the Lasso by returning to the
point where you started drawing the Lasso. If you release the mouse
button before completing your selection with the
Lasso Tool
, Pho-
toshop will close the selection for you, by adding a straight line from
where you released the mouse button to the starting point.
When we click on the
Refine Edge
button on the
Options Bar
, it will take us to a new panel
where we can modify our selection.
