Infrared compensation index
®
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 focusing index on the lens
barrel. (Some lenses, including the Reflex Nikkor, do not need
compensation.)
After focusing 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 set
at 00.).
