P3D Re Keystoning

[abram klooswyk <abram.klooswyk@xxxxxx>]

An often not mentioned drawback of to-in (converging
camera optical axes) applies only to us mortals who
do hand mounting making small errors, but doesn't
apply for the professionals or with digital images.

It is the fact of consuming out (is this English? I mean
exhaust, finish up) all "tolerance space".
We know that the visual system tolerates small height
errors and very small rotational errors, and some
limiting values for them have been published.
>From there has been argued that to-in is acceptable
up to so-and-so many degrees.

But in doing so, using the "tolerance space" for the
keystoning produced by to-in, remember that there
is little or no room left for the ordinary errors me and
you make, any additional error will be too much.
Happy mounting!
