adjustments
The body of 35mm cameras with interchangeable lenses have an ISO
selection dial, a focal plane (shutter speed dial), a frame indicator, a film
release, and a light meter. Focus rings and aperture rings are usually part of
the lens.
ISO selection
dial
The International Standards Organization rates each film for sensitivity by
assigning it a numerical code. Located on top of a camera body is a small
dial with numbers that incrementally increase or decrease by hundreds, for
example, 200, 400, or 1000. Set the dial to the number that most closely
corresponds to the ISO ratings on the film cassette you are using.
Some
cameras require the operator to lift the dial before turning it to the
appropriate ISO number.
Figure 7-10 is an example of a film-speed dial.
