Note
When selecting the hair it's important that you don't include any areas where you
can see through to the background ( Figure 1.5 ) . This is very important and a key
part of making a great selection using the Quick Selection tool. Option/Alt-drag
over any areas in which you can see the background to remove them from the se-
lection ( Figure 1.6 ).
