Thankjs for all your kind remarks. The address where you get the clever
oscilloscope program is...
http://wwwhost.ots.utexas.edu/mac/pub-mac-sound.
html#digital-oscilloscope-21. ... You download it off the net.  It was
invented by a nice Swiss man, Hansruedi Baer, who donated it to the public
domain. It is intended by him to analyze audio waveforms for distortion but
it does all sorts of nice things. It is a general purpose oscilloscope,
very fast since computers today have clock speeds in  the VHF region.
     As per speed of response of CDS cells ,they are very fast, fast enough
to fire a strobe flash and a slave to overlap at 1/1000 sec. No
problem.Commercial shutter testers use them. In fact you should  buffer
them with a capacitor to keep them from undulating with the sine wave of
fluorescent light  in a good EE camera design.
   Since I seem to be in a writing mood tonight, here is another thing that
I want to tell about . About 1978 a very bright Hungarian man age about 70
visited me at Spartanburg, driving a VW camper. He was an inventor. He
showed me a most unusual stereo camera he had built. It took full frame
35mm stereo working this way: First exposure was frames one and three. Next
was two and four, third stereo pair was 3 and 5 and so on. It had two
Nikormat Copal Sq focal plane shutters and a modified Nikon wind. The
interesting feature  was the lenses were a pair of 28mm Retrofocus F2.8
wide angles, Nikon I think.The guy, I forgot his name, was certain that
good stereo had to be wide enough so you ignored the frame edges  of the
images and lived INSIDE the 3d environment. .
   To keep the two lenses from being very far apart the film went looping
toward the front of the camera, towards the lens. You see... when frame 1
and 3 were in place to shoot, Frame 2 was in the little loop. The system
was meant to be used as a filmstrip !!! He had made a clever projector with
film running horizontally and it also had wide angle lenses. He set it up
and showed a series he had shot in the Grand Canyon against my living room
wall. No screen I had was big enough.  I thought the system was extremely
good. Of course he wanted help in marketing it. I tried to be encouraging
but I did tell him frankly that the US camera industry was moribund and
suggested Japan. I'm not connected with manufacturers but I did  write for
him letters of introduction to  such people as Jason Schneider, Herbert
Keppler, Jacob Deschin and John S. Carroll that I knew, praising his unique
stereo camera. I did all this for free, hoping he'd get a break.
    I never heard anything more about this unusual 3D system. The poor man
suffered from  a rather bad case of congestive heart failure in 1978, so I
assume he is no longer alive. I'd like to know what happened, and hopefully
see something made of this idea. Of course, you'd have to search
patents.That's your job.  He may have patented it. I don't know. I wish
something had come of it. It is a much more sensible invention that the
Kodak Disk Camera or Polaroid Instant Movies!..Well..its  time to look at
my e-mail again ..Bye   Ed Romney
