Adobe Photoshop CS5 One-on-One

(やまだぃちぅ) #1

  1. Reverse the selection. You’ll recall that what
    we really want to select for our composite is
    the manly saw and the manly hand wielding
    it. So now that we’ve gone to such lengths to
    select the background, choose Select→Inverse
    to switch the areas that are and are not selected.
    As you can see circled in Figure 3-29, the saw blade,
    that troublesome area that caused problems earlier,
    is still missing from the selection. Don’t fret and try
    to slice things up with your incomplete power tool.
    We can remedy the problem of the missing blade by
    employing some of Photoshop’s other useful tools
    in the next exercise. For now, press Ctrl-Shift-S
    (�-Shift-S) and save your file as “My toothless saw.
    Figure 3-29. psd.” Then click OK.


Quick Selection and the Quick Mask Mode


Adobe is slow to add selection tools. Seventeen years after introduc-
ing the world to the magic wand, it ushered in the speciously named
quick selection tool. (Little about its performance suggests that
you’ll complete your selection chores faster.) In contrast to the magic
wand, the quick selection tool is sensitive not to color ranges but to
edges, which are sudden transitions from dark to light. Paint inside
the element you want to select and Photoshop increases the selec-
tion outline to what it considers the outlying edges of that element.
In this lesson, we’ll take a look at how well the quick selection tool
handles our problematic saw blade from the preceding exercise.
We’ll use Photoshop’s venerable History panel to save selection
variations along the way, just to be safe. I’ll also show you how you
can check the quality of your selections by reviewing them in the
quick mask mode, and address any problems you might see there.


  1. Continue with the files from the preceding lesson. We’re
    still trying to fix that selection outline we began in the
    last exercise, so I’m hoping you still have My toothless
    saw.psd and Ad composite.psd open and the selection on the saw
    image still active. (If you need a catch-up file, open Toothless-
    Saw image.jpg instead. Then choose Select→Load Selection,
    choose Bladeless from the Channel pop-up menu, and click
    OK to resume where we left off in the last exercise.)
