Creating a Selection with Color Range

Recall how the Magic Wand  works.  The Selection is created by analyzing a base color (which you designate by {Clicking} on it) and a range of related colors you determine by setting Tolerance.  You can also use the Select by Color Range  function by selecting Select/Color Range.  The Color Range dialog-box appears.

Color Range  Dialog-Box

The Color Range  dialog-box consists of a Selection option drop-down menu, Fuzziness controls (for fine tuning the range of your Selections ), an Image Box with the current image or Selection, Selection Preview options and 3 Color Picker s.

Select

Use the items in this menu to define how you are going to create your Selection.  You can choose by color range (from Reds, Yellows, Greens, Cyans, Blues, Magentas), by Sampled Colors (colors you select with the Color Picker s), by Contrast  (Highlights, Midtones, Shadows), and Out of Gamut (which applies to images created for Print.)  Generally, you’ll use Sampled Colors.

Fuzziness
Use the Fuzziness to increase or decrease the selected color range.

Selection or Image
Check Selection to display Selection data in the Image box.  Check Image to display the image.

Selection Preview
Select from None, Grayscale , Black Matte , White Matte, and Quick Mask  to display the Selection area and control how the Selection is displayed within the Image Window .

Color Pickers
There are three color pickers.  Use the Color Picker  without a “+” or “-“ symbol to select one color as the basis for creating your Selection and define the range by using the Fuzziness slider.  To add additional colors to your Selection use the Color Picker with the “+” sign.  To remove colors from your Selection use the Color Picker with the “-“ sign.

Invert
{Click} Invert  to reverse your current Selection.

Restore the fudog image to its initial state.  Select Select/Color Range .  Make sure Selection is checked below the Image Box.  Select the Color Picker  without any signs.  You can use the Color Picker within the Image Box or on the Image itself.  {Click} on the Black Area of the fudog image.  A black mask covers most of the statue in the Image Box, indicating the unselected area.  {Click} and drag the Fuzziness slider to a across its range to see how the selection is affected.  Adjust the Fuzziness slider so that the statue is almost completely black and the background almost completely white.  {Click} Invert  to reverse the Selection.  {Click} OK.  A Selection marquee surrounds the statue.
