          As we said earlier, there are many selection options in Photoshop, each with its own
          advantages and disadvantages. You have already used the marquee tools and lasso tools
          to select general areas of images.
              Many images have both hard and soft edges, and/or very fine detail that needs to
          be isolated from its background (think of a model’s blowing hair overlapping the title
          on the cover of a magazine). In this type of image, other tools can be used to create a
          very detailed selection based on the color in the image.
              Rather than simply deleting pixels, as you did for the lightning image, another
          option for isolating an object with a path is to create a layer mask that hides unwanted
          pixels. Areas outside the mask are hidden but not deleted, so you can later edit the
          mask to change the visible part of the image.

            1.  With aftermath.psd open, hide all but the Skyline layer. Click the Skyline
               layer to make it active.

            2.  Choose the Magic Wand tool (under the Quick Selection tool). In the
               Options bar, make sure the New Selection button is active and set the
               Tolerance field to 32.

               The Magic Wand tool is an easy way to select large areas of solid color. The first four
               options in the Options bar are the same as those for the Marquee tools (New Selection,
               Add to Selection, Subtract from Selection, and Intersect with Selection).

               Tolerance is the degree of variation between the color you click and the colors Photoshop
               will select; higher tolerance values select a larger range based on the color you click. If
               you’re trying to select a very mottled background (for example), you should increase the
               tolerance; be careful, however, because increasing the tolerance might select too large a
               range of colors if parts of the foreground object fall within the tolerance range.
               The Anti-alias check box, selected by default, allows edges to blend more smoothly into
               the background, preventing a jagged, stair-stepped appearance.
               When Contiguous is selected, the Magic Wand tool only selects adjacent areas of the   Note:
               color; unchecking this option allows you to select all pixels within the color tolerance,
               even if some pixels are non-contiguous (for example, inside the shape of the letter Q).  Anti-aliasing is the
                                                                                        process of blending shades
               By default, selections relate to the active layer only. You can check Sample All Layers to

               The Refine Edge button opens a dialog box where you can use a number of tools to   a raster image.
