What is the normal frames-per-
second rate for motion pictures?
1. 12
2. 24
3. 48
4. 96
10-2.
What characteristic of human
vision contributes to the illusion
of motion in motion-picture
photography?
1.
Persistence of vision
2.
Image perception
3.
Chromatic stimulation
4.
Visual frequency response
10-3.
With normal persistence of vision,
the "after image" lasts approxi-
mately what length of time?
1.
1/2
2.
1/4
3.
1/10
4.
1/50
10-4.

motion-picture film is referred
to by what term?

Cut
2.

10-5.
What is the standard projection
speed for a motion-picture film?

8 fps
2.
16 fps
3.
24 fps
4.
36 fps
10-6.
A motion-picture film shot at
which of the following fps rates
produces the illusion of slow
motion?
1.
6 fps
2.
12 fps
3.
24 fps

10-7.
What is the normal focal-length
lens for a 16mm camera?

3.
25mm
4.
16mm
10-8.
What is the result when a motion-
picture camera is panned with a
polarizing filter over the lens?
1.
Variable darkening of the
sky as the camera is panned
2.
The polarizing grids cause
the image to flicker
3.
Excessive sk y contrast results
from the inability of the
filter to rotate at the same
rate as the camera is panned
4.
Interference lines caused by
the polarizing grids and the
frame lines being out of
synchronization
10-9.
Which of the following is NOT
an exposure controlling factor
in motion-picture photography?
1.
Film speed
2.
Shutter speed
3.
f/stop
4.
Lens filter
