Re: Twin 35

Jim Norman writes about his twin Conon EOS Rebel X 35s mounted
vertically.  I am curious if he is using slide or print film with
these cameras.

Quite a few photographers are using twin cameras in vertical
orientation.  I saw Otto Walasek using his twin autofocus Minoltas
in this configuration with 100 mm lens, taking stereo portraits of
the models.  Still, the 3 3/8 lens' separation is hyper enough
to exclude a wide range of photography and a normal separation
stereo camera is needed, especially in moderate close-ups with
a normal/wide lens.

For those who shoot standard stereo format slides, vertically oriented
stereos end up in Realist format mounts.  A normal stereo camera 
(Belplasca or RBT full-frame, for example) is needed for the landscape 
composition.  And, no, a twin rig or a regular stereo camera is not 
useless for landscapes.  Hyperstereo is not the only way to record distant 
landscapes.  I just saw a  large variety of wonderful landscapes in PSA, 
all recorded with regular stereo cameras.  The trick is to frame your 
landscape properly, including some foreground.
