If the mirrors themselves introduced keystoning, then wouldn't 
cameras such as the Loreo/Argus and many beam-splitter designs have 
the same problem? (Or worse since these systems bounce light off of 
two mirrors?) I have discovered that keeping this rig level and 
aligned is a challenge.  I especially need to find a way to have a 
bubble level for the horizontal plane of the two cameras visible 
while shooting.  Jim Harp
