[tech-3d] Re: Stereo Base Calculation

["Abram Klooswyk" <abram.klooswyk@xxxxxx>]

There is a scene out there reaching from near to far.
You want to take a stereopicture of it. 
When you have chosen a base and pressed the shutter,
the deviation is fixed on the film. When you rather
wanted another deviation, you should have changed the base.

For a given scene and standpoint:
Either you choose the base and get a deviation,
or you choose the deviation and get a base.

A formula which pretends to give the right base
but leaves to guessing which deviation to put in
is just as useful as a formula which calculates
the right deviation after you have guessed the
base. In fact, it is one and the same formula, 
which some call "General Solution".
Seldom a better paradox was formulated after Zeno,
and as with Zeno the Solution is a mystery.

My advice: stick to General Motors, General Electric
or General Eisenhower. 
(One of them was a stereographer :-).)
