Hi Fred,

Here is the VERY quick version of the instructions. NOTE: horizontal and
vertical alignment is crucial... 

Split the RGB channels of the left image, then copy the R from that
image.

Split the RGB channels of the right image, then paste the R from the
left image over it - BUT - before you finalize that paste, set the
paster R to 50% transparency so you can align it to the view you are
pasting over. A good rule of thumb (that will nto be best in all
situations, but is a good place to start) is to set it so that an object
in the view that is closest to the camera lines up with it's
counterpart. Set it back to 100% (non-transparent) and recombine the RGB
parts of the right image.

Trim away "bad" edges and voila! 

Enjoy!! =)
