Dear John,

Well yes,two strips in camera, elegant but how to vary the interaxials?
John A. Norling had designed this camera of elegance for 3-d filming in 1956.
Here is one of the elegant camera of today:

<PRE>Thank you so much for the explanation of why filmmakers would use convergence&nbsp;
instead of shift.&nbsp; Perhaps you and I need to build some shift lenses.&nbsp; What&nbsp;
format would these be for?&nbsp; 35 mm?&nbsp; 70 mm?&nbsp; I think in most cases you might
be able to use shift lenses with the standard two-camera setup that looks&nbsp;
through mirrors.&nbsp; It could be fun to try!&nbsp; I think we would have to use&nbsp;
encoded steppers or servos since the cameras are separate.&nbsp; If it were one&nbsp;
camera with two film strips we might be able to do something much more elegant.
