CAMERA VIEWPOINT [FILM TECHNOLOGY]
Camera viewpoint
The angle from which
it sees the subject. As well as the lens, which decides how much of each scene we see.
CAMERA TRAP [FILM TECHNOLOGY]
Camera trap
[Film Technology]
An opening arranged with in scenery through
which a camera can shoot (often remaining unseen by other cameras) and so
increase the potential camera viewpoints. Such
devices as pull-aside drops shutters, hinged wall pictures, sliding
panels are used. One solution to allow shot
variety, is to construct the scene with all the
required features, and to circumvent any obstacles by providing peep holes
through which the cameras can shoot otherwise in accessible parts of the acting area. Camera traps in the form of sliding wall panels or hinged
wall panels. Camera access opening into a tiny claustrophobic
situations, where there is just about for the camera to peep in[claustrophobic camera peeping].
CAMERA STEADINESS TEST [FILM TECHNOLOGY]
Camera steadiness test
[Film Technology]
Sophisticated
means existing accurately checking and measuring image
displacement. But a practical method used by most camera mechanics is to
photograph a grid or radiating
pattern of lines with the camera rigidly mounted on a particularly
robust stand, then to rewind the film and
expose it again, displacing the camera slightly, horizontally and vertically.
When film has been processed, any unsteadiness shows up as relative movements
between the two exposures. This is the only way
of pinpointing a camera fault. By using a pattern consisting of a series of
radiating black and white lines a ‘chrysanthemum’, double exposed image unsteadiness will show as a moiré pattern and may be readily discernible on the screen. Another system uses cranked
lines which are reversed between takes thus giving an arrow like pattern
from which unsteadiness may not only be seen but also quantified. The degree of
image steadiness to be expected of a camera vary according to the make, type, state of
serviceability and frames per second rate
required. A simple camera movement employing a pull-down
claw only can never produce image as steadily as a camera with double pull-down claws on each side and double close register pins. Some cameras are
acceptably steady-at 24-60fps but not at 80 fps while others, in good
condition, can be expected to be steady, even for double
exposure process printing, at 128 fps.

CAMERA SHADOW [FILM TECHNOLOGY]
Camera shadow
[Film Technology]
The camera’s shadow
falling on to the subject on being seen in the
shot. If a close camera cast shadows on the subject, a more distant position with a narrow lens angle can clear the problem.
CAMERA SERIAL NUMBER [FILM TECHNOLOGY]
Camera serial number
[Film Technology]
Individual cameras
always be identified by serial number which is either engraved or the camera body, or on a plate attached to it. The
location of serial number is not always obvious especially where they are
hidden by a cover or component or are inside the camera. A knowledge of where
numbers are to found is particularly necessary when passing through
international custom posts.
CAMERA SCRIPT [FILM TECHNOLOGY]
Camera script
[Film Technology]
[Film Technology]
A
camera script also includes, the film operational
information, film technical information
and film staging information required for production treatment along with the actor’s lines (dialogues)
and basic action (moves). This is a full record of picture
treatment and sound treatment for the production. On one half of the page are the dialogue, stage instruction,
action, lighting,
sound treatment etc.. On the other half are
details of the camera used, shots required, picture transitions [cuts,
mixed/dissolves, wipes]. It is an essential document for production planning and reference, but usually too
detailed to be followed by a pre occupied cameraman,
who uses various information sheets instead.
CAMERA RIGHT [FILM TECHNOLOGY]
Camera right
[Film Technology]
Right side of the cameraman. This is a camera
orientation. The description left and right side of a camera is as seen from the rear as seen by cameraman.
CAMERA REHEARSAL [FILM TECHNOLOGY]
Camera

[Film Technology]
1) Dry run
rehearsal.
2) Blocking out
rehearsal.
3) Final run
through rehearsal.
4) Intermediary
run through rehearsal.
5) Dress
rehearsal.- Which is direct replica of the version to the re-content
with complete wardrobe.
