Camera Tilt Compensator                                                               45



                             Using the Camera Tilt Compensator






                          The Tilt Compensation Tool works by having an
                     item in the picture that is known to be plumb level.
                     In the picture on the right it is a piece of tape on the
                     wall that was placed with the help of a laser level. You
                     could also use a plumbline, or create a grid pattern on
                     the back of the wall. Anything that will show a vertical
                     plumbline in the picture.


                          Then, no matter how tilted the picture is, Posture
                     Pro can compensate for it.


                          Here's how it works:


                          Import posture picture into Posture Pro as you
                     normally would. Make sure there is something in the
                     picture that you know to be vertically level.


                          Next, click on the check
                     box for either the AP or lateral
                     in the Camera Tilt Compensa-
                     tion area of the Control Panel.


                          This will cause the picture
                     to zoom in, and the mouse ar-
                     row changes to a crosshair.


                          Make one click at the top
                     of the reference plumbline in
                     the picture and a second click
                     at the bottom of that line. After
                     the second click the picture will
                     zoom out and the amount of
                     deviation will be noted in the
                     text box to the right of the AP or
                     Lat indicator in the Camera Tilt
                     Compensation Box.
