The key to this is the viewing distance of the print.
When a print is viewed from a distance equivalent to the
lens focal length the perspective looks right. Of course,
for an enlarged print this distance is the focal length
times the enlargement magnification. The distance the
****trait is taken from should result in a reasonable viewing
distance for the print. Most "normal" focal length lenses
have a FL about equal to the diagonal of the format but,
except for rather large prints, the viewing distance of a
print is typically more than this. For common size prints,
say 8x10 or smaller, the viewing distance will usually be
around twice the diagonal of the print, for small prints
even more.
The perspective can be used to deliberately modify the
pro****tions of a face. Moving further makes the nose look
smaller and the ears look bigger, close up, the nose looks
bigger but ears are diminished. All a matter of taste and
judgment.
Actually, a normal focal length or even wide angle lens
will produce the same perspective if the camera distance is
the same. The difference is in the amount of the negative or
transparency the desired image occupies.
