This page presents the test series with magnification varying
inversely with focal length. Assuming you view all images at the
same distance from your monitor, the effect is approximately the
same as viewing the 50 mm images from twice the distance as
the 28 mm ones, and the 100 mm images from twice the
distance as the 50 mm ones.
The intent is to see the effect viewing distance has on our
perception of perspective, not necessarily to view the images
from the "correct" viewing distances. (Obviously,
28 mm is not quite 1/2 of 50 mm, so apparent viewing
distance for the 28 mm images is a bit close relative to
the others, and anyone who followed the thread on 3D perspective
and "squish" in the June-July '99 Pentax discussion list
should recognize that by only taking focal length into account,
these viewing distances can only be rough approximations.)
