INFRARED PHOTOGRAPHY
In
infrared
photography,
the
plane
of
sharpest
focus
is
slightly
more
distant
than
the
one
produced
by
visible
light
and
seen
through
the
viewfinder.
To
compensate
for
the
shift in focus, the lens has a curved red line on the lens barrel. After focusing the image
sharply
through
the
viewfinder,
check
the
focused
distance.
Then
turn
the
focusing/
zooming ring to the left until the red line lines up with the prefocused distance,
