Step Three:
Now you'll need to do two things:
(1) make your brush size smaller, and
(2) turn on the Auto Mask checkbox. The
Auto Mask feature is really what makes
this all work, because it will automatically
make sure you don't accidentally make
the object in your image that you want
to remain color, black and white, as long
as you follow one simple rule: don't let
that little plus-sign crosshair in the center
of the brush touch the thing you want to
stay in color (in our case, it's the bouquet
of flowers). Everything that little crosshair
touches turns black and white (because
we lowered the Saturation to -100), so
your job is to paint close to the flowers,
but don't let that crosshair actually touch
the flowers. It doesn't matter if the edges
of the brush (the round rings) extend over
onto the flowers (in fact, they'll have to,
to get in really close), but just don't let
that little crosshair touch, and you'll be
fine. This works amazingly well (you just
have to try it for yourself and you'll see).
Step Four:
Here, we've painted right up close to
the bouquet and yet the flowers and
even the green leaves are still in color
because we were careful not to let that
crosshair stray over onto them. Okay,
now let's use a similar technique in a dif-
ferent way to create a dark, dramatic
effect using the same image. Start by
pressing the Delete (PC: Backspace) key
to get rid of this adjustment pin and
start over from scratch with the original
color image.
