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 mmb. 35 mmc. 50 mmd. 65 mm

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 / 2.8b. f / 8c. f / 5.6d. f / 22

4. Using the same f / stop scale, what f / stop would produce the minimal, or least depth of field?a. f / 22b. f / 5.6 c. f / 2.8d. f / 11

Shutter SpeedThe 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

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 Blackb. Minimum Time for Maximum Blackc. Gray Scale for Maximum Densityd. 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 sharpb. The runner will be blurryc. The runner would have maximum depth of fieldd. 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 Bathb. Developer, Perma Wash, Fixerc. Developer, Stop Bath, Fixerd. D-76, stop bath, Fixer

9. The darkroom trays in the Foothill College are color-coded this way:

a. White, Red, Grayb. Red, White, Grayc. Gray, Red, Whited. 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 / 11D. 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 LensB. 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?
