Adobe Photoshop CS5 One-on-One

(やまだぃちぅ) #1

  1. Revert the image. To get rid of the quick
    selection version of the saw blade selection,
    we need to get back to where we started in
    this exercise:

    • If you’re using the ToothlessSaw image.
      psd file, choose Select→Load Selection,
      select the Bladeless channel again, and
      click OK.

    • If you’re using the file from the preceding
      exercise, return to the History panel and
      click the state that reads Select Inverse.
      Either way, you’ll end up back where you were
      when we finished with the magic wand tool.



  2. Select the lasso tool. Press the L key to return
    to the standard lasso tool. Press the Option
    (Alt) key so that you’re deselecting (you’ll see
    the telltale minus sign), and draw around the
    blade area as shown in Figure 3-39 to dese-
    lect the blade.

  3. Switch to the polygonal lasso. Press L again
    to switch to the polygonal lasso tool. Press
    and hold the Shift key to add to the selection,
    and click inside the body of the saw and then
    at the corners of the blade, following the path
    indicated in Figure 3-40. When you get back
    to the black area inside the saw, double-click.
    Don’t worry about the individual serrated
    blade edges; the focus is blurry enough that
    trying to grab each tooth of the saw is an
    exercise in insanity. Even I wouldn’t try it.
    Instead, cheat your line along the edge.

  4. Check the new selection in the quick mask
    mode. Press the Q key to quickly return to
    the quick mask mode, and then once again
    turn off the next to the RGB composite
    in the Channels panel to see the black and
    white mask.
