Copy and Paste Selected Pixels
            In addition to dragging an entire layer with the Move tool, you can also use a variety
            of selection tools to choose only certain areas of a layer that will be copied. In this
            exercise, you use the most basic selection tool — the Rectangular Marquee tool.
             1. With aftermath.psd open, choose View>Fit on Screen to show the entire
                 image centered in the document window.

             2.  Open the fi le Skyline.jpg from your WIP>Movie folder.
             3.  Choose the Rectangular Marquee tool in the Tools panel and review the
                 options in the Options bar.
                                                                       A B C D     E         F     G  H
                 By default, dragging with a marquee tool creates a new

                 selection. The buttons on the left end of the Options bar

                 define what happens if you draw more than one marquee.
                    A New Selection creates a new selection each time
                       you create a new marquee.
                    B Add to Selection adds the area of a new marquee to the existing selected area.
                    C Subtract from Selection removes the new marquee area from the existing selection.
                    D Intersect with Selection results in a selection only where a new marquee
                       overlaps an existing selection.

                    E Feather (soften) the edges of a selection by a specified number of pixels.
                    F  Choose a normal selection, a fixed-ratio selection, or a fixed-size selection.


                    G When Fixed Ratio or Fixed Size is selected, enter the size of the selection in

                       the Width and Height fields.

                    H  Click this button to reverse the Width and Height fields.
             4.  Choose the New Selection option in the Options bar. Click outside of the
                 top-left corner, drag down past the bottom edge of the image, and drag
                 right to create a selection area that is approximately 8.5″ wide.         Note:
