I'll try and be more clear....

                                  --- focused area
                            ____ /
   camera                 _/    \_
     oo                  /     /  \
    [__]-               (    ()    )
      |                  \_   |  _/|
      |                    \__|_/  |
      |                       |    |
      \______________________/ \__/
                   /             \
   Focal Distance-/               \----X
                                       ^
my problem is how to figure X out  ---/
besides pulling out a real camera and focusing
on something at the same distance.
Are there any tricks to this?
or is it just trial and error?

Please, please help me
TIA,  Sergio Rosas
