®
When
you
shoot infrared film, note that the plane of sharpest
focus
is
slightly farther away than that in visible-light photo-
graphy.
As
a rule of thumb,
you
can compensate for this shift
in
focus
by
referring to the infrared compensation index
(in
the
form of either a dot or a line) near
the
focus
ing
i
ndex
on
the
lens
barrel.
(Some
lenses, including the Reflex Nikkor,
do
not
need
compensation .)
After focus
ing
the image sharply through the viewfinder, check
the focused distance and turn the focusing ring to the left until
the red infrared compensation index lines
up
with the prefocused
distance.
Be
sure to shoot with appropriate filter, such
as
the
R60
, etc
.,
(In this photo, the subject-to-camera distance
is
