Canon AUTO ZOOM 1218 - Manual (Page 36)

Manual Aperture Control
The aperture can be mantially controlled by switching the aperture
control ring to " MANUAL" and turning it in the direction of the
arrow. In manual operation, any desired f/stop can be set by turn­
ing the ring while looking at the f/stop scale inside the viewfinder.
The smallest aperture opening is f/22, i.e., the position of the red
mark on the right side. Use this method when shooting against
the light or when you wish to stress high-key or low-key effects.
1^ The exposure meter needle moves, even in the case of manual
operation, only when the mercury batteries are loaded.
4 Open one and a half f/stop further when you shift the filming
speed selector from "18” to "SLOW MOTION”.
Fadings
Fadings are used to show the elapse of time or a change in scene,
for instance, when the scene on the stage changes at the end of
a theme.
You can perform fade-ins and fade-outs with the combined use of
the aperture control ring and a neutral density (NO) filter. Use
a tripod when you perform fadings.
1
Attach an NO filter over the lens. By using an NO filter and
‘ making a larger difference between the proper f/stop and the
minimum f/stop of f/22, fadings can be performed smoothly and
effectively.
O Confirm the proper f/stop by aiming the camera at the subject
^ with the aperture control ring set at "AUTO”.
Q Switch over the aperture control ring to "MANUAL”. Turn the
” aperture control ring from the minimum f/stop to proper f/stop
in the case of fade-in, and from the proper to minimum f/stops
in the case of fade-out.
4 Fading times of 1-1.5 seconds for a fast changing scene, and
2-3 seconds for a slower changing scene are advisable.
