effect, such as rendering a certain range in sharp
focus or el1]phasizing a subject aga inst an
out-of-focus background. In this case, set the
desired f-number on the aperture ring, then use
the match-needle system to set the shutter
speed for proper exposure at the
setting.
Small
f-numbers yield a relatively shallow field of
sharp focus, as in example 0 at right, while
large f-numbers give greater depth of field, as in
example
E.
To judge depth of sharp focus, use
the depth -of-field scale (see p
.
31) or stop-down
button
(p.
32).
No matter how the camera is used, it is
important to support it (see p. 21) and release
the shutter properly
(p.
33). In accordance with
the above principles, the match-needle indica-
tion may of course be adjusted (as indicated on
p. 25) or exposure set manually with or with-
out reference to a separate meter.
