Adobe Photoshop CS5 One-on-One

(やまだぃちぅ) #1

Photoshop gives you the raw information you need to accurately
define the edges in the image. Then it’s up to you to figure out how
to assemble the pieces. Fortunately, you can do so using not just a
few selection tools but virtually every function in Photoshop’s ar-
senal. And because a mask is a channel that can be saved as part
of a TIFF or native PSD file, you can recall or modify the selection
outline any time you like.


Using the Color Range Command


Photoshop’s Color Range command uses a masking metaphor to
generate selection outlines. In this regard, it serves as a bridge be-
tween the worlds of selections and masks, not to mention as a won-
derful introduction to our lesson.


Essentially a sophisticated version of the magic wand, Color Range
lets you adjust the range of colors you want to select until you
arrive at an acceptable, if not perfect, selection outline. And it
does so dynamically, so there’s no need to start a selection over, as
you sometimes must with the wand. Color Range also interprets
luminosity values in a more sophisticated manner than the wand,
which results in smoother, more credible selection outlines.

  1. Open an image. Open the
    file Superlips.psd which is
    located in the Lesson 10
    folder inside Lesson Files-PsCS5 1on1.
    This striking image, displayed in
    Figure 10-5, comes from photogra-
    pher Lvenl of the Fotolia.com image
    library. In the course of this exercise,
    we’ll not only change the color of
    these lips to a nice cherry red but
    successfully mask them against a
    new black background.

  2. Press the D key. By now, you know
    this resets the foreground color to
    black. But what you might not know
    is that the Color Range command
    uses the foreground color as the basis
    of a selection. You don’t always have
    to start with black; doing so merely
    assures that you and I start on the
    same foot.
