Quiz 1: The Camera - Photo 1
Name: Date:
Circle the correct answer:
1. On a 35mm camera, the focal length considered the normal lens is a ____________ mm.
a. 24 mm
b. 35 mm
c. 50 mm
d. 65 mm
Shutter Speed
The length of time film is exposed to light is controlled by the shutter speed control. This duration
of time is also called the shutter speed. The term shutter speed can also be referred to as a “stop”
because of the principle of “reciprocity.”
2. In the following list of shutter speeds, the principle of reciprocity is working. What is the
missing shutter speed?
1 1 1 1 1 1 1 1 1 1 1 1
2 4 8 15 30 60 125 500 2000 4000 8000
Aperture or F-stops control the “volume, or amount” of light that reaches the film. F/ stops also
control depth-of-field. With this as a hint, choose the correct answers.
f 2.8 f/ 4 f/5.6 f/8 f/11 f/16 f/22
Big Aperture Small Aperture
3. Which f/ stop above would produce the most depth-of field?
a. f / 2.8
b. f / 8
c. f / 5.6
d. f / 22
4. Using the same f / stop scale, what f / stop would produce the minimal, or least depth of field?
a. f / 22
b. f / 5.6
c. f / 2.8
d. f / 11

5. Making a test strip before making a photogram was important because the test strip told us the
______________________ _________________ for maximum ________________.
a. Maximum Time for Minimum Black
b. Minimum Time for Maximum Black
c. Gray Scale for Maximum Density
d. Longest Time for Maximum White
6. What would happen if you took a picture at 1/15th of a second of some one running from left to right in
your viewfinder?
a. The runner will be tack sharp
b. The runner will be blurry
c. The runner would have maximum depth of field
d. Both A & C
7. 35 mm cameras, in general, use focal plane shutters. What is one limiting factor of the focal plane
shutter?
a. The focal plane shutter synchronizes an electronic strobe at every shutter speed, thereby making it
difficult to decide what shutter speed to use in an outdoor lighting situation.
b. The focal plane shutters main disadvantage is the inability to synchronize at every shutter speed
with an electronic strobe.
c. A focal plane shutter has no limiting factors.
d. None of the above.
8. The chemistry used to create a black and white print in the darkroom is as follows:
a. Developer, Fixer, Stop Bath
b. Developer, Perma Wash, Fixer
c. Developer, Stop Bath, Fixer
d. D-76, stop bath, Fixer
9. The darkroom trays in the Foothill College are color-coded this way:
a. White, Red, Gray
b. Red, White, Gray
c. Gray, Red, White
d. None of the above
10. Different combinations of shutter speed & f /stop can produce the equivalent
exposure. What is the equivalent exposure to 1/250th of a second at f/ 11 from the
choices below?
A. 1/500th of a second at f / 8
B. 1/500th of a second at f / 16
C. 1/500th of a second at f / 11
D. None of the Above.

Which sentence best describes the out-of focus look of a photograph? The “blurred” area in a
picture is controlled by the shape of the aperture of the lens, and the focal length of the lens.
A. The Japanese word “bokeh” refers to the way an the out of focus part of a photograph
looks in a photograph.
B. The out of focus portion of the photograph is referred to as “layered.”
C. The blur is called the picture’s hyper-focal distance.
D. None of the above, you are messing with my mind. Stop it!
The mathematical formula used to calculate the f / stop of any lens is:
A. e = mc2
Focal Length of Lens
B. f stop = ——————————
Aperture Diameter
Aperture Diameter
C. f stop = ——————————
Focal Length of Lens
(Subject Distance ) X (Focal Length)
D. Focal Distance = ———————————————
(Subject Distance) -— (Subject Diameter)
The Twin Lens Reflex camera is a medium format camera, manufactured by Rolleiflex.
Hasselbad is a Swedish popular medium format camera, too. Both use the medium-format film
size is of 2 1 / 4” by 2 1 / 4” inches square. What is the normal lens on a medium format
camera?
