Adobe Photoshop CS5 One-on-One

(やまだぃちぅ) #1

  1. Maximize the Radius values. Left to its own de-
    vices, the Shadows/Highlights command tends to
    sharpen an image. To prevent an overly sharpened
    effect, raise both Radius values—one under Shad-
    ows and the other under Highlights—to 100 pixels.
    A large Radius value distributes the effect, result-
    ing in the smoothest possible transitions between
    our friends the highlights, shadows, and midtones.

  2. Modify the Tonal Width values. The two Tonal
    Width options control the range of brightness val-
    ues that Photoshop regards as shadows or high-
    lights. Because our image consists of slightly more
    shadows than highlights, we want to lightly nar-
    row the definition of the former (the shadows) and
    barely widen the latter. So reduce the Tonal Width
    for Shadows to 40 percent and increase the Tonal
    Width for Highlights to 70 percent.

  3. Increase the amount of shadow. Having tempered
    the shadows by decreasing the Tonal Width and
    increasing the Radius, the dark shades can tolerate
    a higher Amount value. Raise the Amount in the
    Shadows section from 30 to 60 percent to increase
    the brightness of the darkest colors in the photo.

  4. Lower the Color Correction value. Much like the
    Saturation value in the Hue/Saturation command,
    the Color Correction option lets you adjust the
    intensity of colors. For the most part, the colors are
    fine in this image, though the reds in the rooster’s
    beak are a bit too intense for my taste. Lower the
    Color Correction value to +10 and leave the other
    Adjustments values as they are. Figure 6-41 shows
    the Shadows/Highlights dialog box with the final
    values entered.

  5. Accept your changes. Click the OK button or press
    Enter or Return to apply your changes and exit the
    Shadows/Highlights dialog box.
