INFRARED PHOTOGRAPHY

In infrared photography, the plane of focus is slightly behind that of visible light.

Consequently, when you are using infrared film in the camera, you have to

compensate for this difference in focus. With the Zoom-Nikkor 35-70mm f/3.5,

two infrared focusing indices are provided for the focal lengths of 35 and 70mm,

You first focus on your subject in the normal way, then read off the camera-to-

subject distance indicated on the focusing

ring.

This distance is then set against

the corresponding infrared focusing index for the focal length you are using. For

intermediate focal lengths, you can estimate the corresponding corrective point,

using the engraved lines as a guide.

The scales on page 25 can be used for determining the amount of adjustment

via the dotted infrared compensation line included

In the same manner as described in the "depth-of-field scale" section, match

the prefocused subject distance (using the B scale) with the focal length and

aperture scate central indicator line (on the A scale). The distance from the

central indicator line to the dotted compensation line represents the amount of

adjustment required Now, turn the lens' focusing ring counterclockwise until

the prefocused distance is shifted as prescribed on the scales.
