[photo-3d] focus and convergence

["ron labbe" <ron@xxxxxxxxxxxx>]

I still believe that focus and convergence ARE normally linked- I didn't
quite understand your response stating otherwise... why would they NOT be
linked in real life?

J.R.>>Converging at different distances than focus does not seem to cause
any
problems for most people as long as the images are aligned and parallaxes
are not excessive.<<

I'm wondering if this is a guess or based on something substantive. And
where is negative parallax excessive? How far off the screen before it
becomes uncomfortable?  It is certainly not the same for everyone... and my
experience tells me that strong negative parallax is what the audience
(generally) wants...

If focus and convergence were not linked it would be a lot easier for people
to learn to freeview.
