Now, let's view the hologram we have created, and the light wave-
   front (the first image we created) side by side. 
 
      Note that the color image is used to indicate the relative light
   phases that occur at each pixel.  The black and white hologram, on-the
   -other-hand is made for photographic reproduction. In the final
   transparency the black areas block laser light, and the white areas 
   become clear portions of the transparency. 
 
       Note that each image must be calculated before it can be displayed. 
   This is because the image file is a table of 32 bit real numbers, and 
   these must be converted into colors first.  The second image is 
   processed only after the first one is displayed, so please be patient 
   with it. 

      Once DIMAGE.COM has begun to diplay the first image, it will NOT
   beep until the second image has been processed and displayed.
