CHAPTER 8. IMAGE TRANSPARENCY 84
I started down at my neck, clicking with the
fountain-pen tool along the edge of my head. You
can see I have progressed up the left edge and am
most of the way across the top of the image. The
series of white circles indicate the locations where
I clicked. It is useful to get as close as you can
to the line between what you want and what you
do not want. It can be helpful to view the image
at a higher magnification to aid in following the
boundary.
I have made it all the way around my picture. On
the last click, instead of simply clicking, I hold
down the control key while I click. This causes
the loop to be closed, joining the last click with
the first click. At this time, I can adjust any of
the dots if I did not place them well. Just click on
the dot and drag it. When the dots are all good
enough, I press ENTER to select the region I have
encircled.
