     Interesting, I'm curious as to how this works, as I thought that
the stereo base on the Realist was set by the spacing of three
5-sprocket film chips.   
     Does the TDC actually provide a format a little narrower than the
realist? (i.e., less than 5 full sprockets?), does it sacrifice film to
permit 5-sprocket images closer to each other? Or are there prisms to
spread the image fields apart and form the images 15 sprockets apart?
