Technical Help

[P3D Ralph Mackenzie <mackenzi@xxxxxxxx>]

Ladies and Gentlemen:
First time writer here.  Please be gentle. :-)
I have been reading the list for a couple of months now and must confess to
being a little awe-struck by the technical knowledge that most of you seem
to have.  Hell, I just point my trusty ( light-tight ) Kodak and take pictures.

A bit of recent traffic concerned itself with a "Super Bowl" broadcast in 3d
( Pulfrich effect ).  I missed that but I remember seeing the half-time show
of an Orange Bowl game many years ago that required some red/green lenses.
I managed to scrape up an old pair of cellophane / card lenses and as I
recall, the depth was OK but the colour suffered.  Which brings me belatedly
to the point:  Can someone explain  Pulfrich and analglyph images to me  (
I'll give you 50 words instead of the usual 25 ).

A second question if I may:
I like to take pictures of sporting events ( recent postings about frozen
action are a happy coincidence ! )  However, the aforementioned trusty Kodak
is limited by its relatively slow shutter speeds and short ( fixed ) focal
length.  I'm toying with the idea of trying the double 35mm number but I
need advice with two issues:  synchronizing the shutters ( @ 1/500 - 1/1000
) and lens spacing.  I have a Minolta AF 7000 and envision getting a second.
These cameras have a remote electronic shutter release which plugs into the
camera via a small jack.  Has anyone ever tried splicing two of these
remotes together, one button / two jacks ?   Secondly, when shooting sports
with the 35mm, I most often use a 70 - 210 mm zoom lens.  Can anyone give a
lead on any calculations of lens spacing for varying focal lengths ?  I
presume that the standard  2-1/2"  +/- is not universal.

I seem to recall some debate a month or so ago concerned with the subject
matter of ( stereo ) competition entries.  Try getting the right lighting
and move a stereo camera right up close to the business end of a race car.
Can you turn technology into art ?

I'm astounded to find so many of you with an interest in stereo photography.
>From the time I was 15 ( back before the dawn of time ) I have felt alone in
this branch of photography.  Home at last in CyberSpace.
