P3D Re: Need Help

["Augusto M. Costa Netto" <augusto.costa@xxxxxxxxxxxxxxx>]

I would like to know if anyone out there can help me find a source of 3D anaglyph adult movies.
Preferably a source that has more than one title, but any information can be helpful.

Thank you.

It is inversely proportional to the distance.  So it is not linear
but "logarithmic".

Just remember the "FBI rule":  Deviation = F x B / I

where F is the Focal length, B is the stereo Base and I is the distance.
At infinity the deviation is zero (it is better to have this as your
base, instead of the window).  

At 7ft (7x12x25.4 = 2130mm) and for the Realist (F=35 mm, B=70 mm), 
deviation = 1.2 mm.

For two distances, I1 and I2, then: deviation = F x B (1/I1 - 1/I2)

Every time you double the distance, the deviation is cut in half.
So a point at 14 feet will have 0.6 mm deviation with the Realist.
