Shooting Techniques to Heighten Effects
1 Zooming
* Zooming creates very interesting effects, but if used too often, it can
become bothersome when the film is projected and can spoil the
performance.
Same as with ordinary ultra-telephoto lenses, even the smallest blur of the
longest focal point part of the lens will greatly mar the picture. When
zooming, use a tripod and the Remote Control Switch 60 or Remote
Control Switch 3 to prevent blur.
WHAT TO CONFIRM FIRST
It is wise to zoom before pulling the trigger to confirm when it will
create the best effect. Decide the composition of the scene before taking
close-ups of the main subject so the audience will enjoy the zooming affect
or switch scenes from close-up to long-shot to show the expanse it has.
CHANGING THE SPEED OF ZOOMING
By using manual zooming, it is possible to lengthen or shorten the
zooming time considerably. For example, it is possible to zoom without
making the audience notice the change of the image magnification, if done
slowly. Also when abrupt changes of zooming speed to maximum or
minimum are necessary, or to maintain a certain magnification, any desired
focal distance may be chosen with the manual zooming.
ZOOMING TO OBTAIN A FOLLOW SHOT EFFECT
The follow shot effect is obtained by following a subject at a certain
distance and it can also be expressed by zooming while keeping the camera
fixed. For example, if a person walking toward the camera is zoomed in on
slowly to maintain the same magnification, his size will not change, but it
has the effect of changing the background.
ZOOMING A LITTLE
The method of stopping the zooming at the required composition
before reaching the maximum is also effective. After shooting for a while
at the middle of the zooming range, zoom again to maximum telephoto in
one take. This also gives variety to your work.
