4. Shooting with Infrared Film
When using black-and-white infrared film nnake a
slight adjustment in focus with the red infrared
index.
For example, focus the subject first, then if the
lens is focused at 5m on the distance scale, turn
the manual focusing ring to align the 5m mark
with the red dot and release the shutter.
When using infrared film, use a deep red
filter as specified by the manufacturer.
The infrared index mark position has
been computed for infrared film usage
with peak sensitivity at 800nm.
Read the manufacturer’s instructions
when using color infrared film.
