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).
