In describing formats, we are specifying the width of an image on the film 
by counting the number of perferations along (one) edge of "standard" 35mm
film.  "Standard" slides are "8-perferations wide", "European format" is
7-perf, Realist camera format is 5-perf, and beamsplitters or half-frame 
cameras are 4-perf.  Because all of these formats use 35mm film, the height
is almost exactly the same, so specifying the width is usually sufficient
among friends.

"Width", as used above is in the stereo camera sense where the long direction
of the uncut film is in the "width" direction.
