[photo-3d] Re: TDC vivid (8-perf w/ 65mm spacing)

[Ralph Johnston/Linda Sherman <copley@xxxxxxxxxxxxxxx>]

The RBT "C" models do this but waste a lot of film.  Also, Gilde has
twinned a pair of Ricoh GR-1 cameras. (See photo in Stereo World)   He set
them at an angle on the bar so that one was behind the other and ended up
with 65mm lens spacing.  These cameras have 7-element 2-aspherical 28mm
f/2.8 lenses and are still available outside the USA.  The price is 250
lb-sterling = $375 plus shipping.  This is for the new model with a filter
holder and time/date option.

I am working on a shutter release solenoid consisting of a coil and a
magnet to allow shutter sync without opening up the cameras.  They would be
taped or velcro'd on top of the cameras and activated via a battery and
pushbutton.  I love my GR-1 and if the solenoid works, I will buy another
and twin them.
