Question 1: What are the four basic parts of a camera?

A:

B:

C:

D:

Question 2: Films are so slow in an early camera that a lens cap could be used as a:

Shutter.
diaphragm.
Camera Obscura.
Lens.

Question 3: The purpose of the shutter is to:

Project the image onto the film.
Control the intensity of the light reaching the film.
Control the length of the exposure.
Hold the film in position for the exposure.

Question 4: The bulb setting on a shutter is used to obtain proper synchronization with flashbulbs?

True
False

Question 5: Which of the following shutter speed settings would be the best choice to blur the action of a race horse moving parallel to the film in the camera?

¹⁄₅₀₀ of a second.
¹⁄₃₀ of a second.
¹⁄₁₂₅ of a second.
¹⁄₂₅₀ of a second.

Question 6: f16 allows half the light to reach the film as does:

f22
f8
f32
f11

Question 7: If you want to limit the depth of field for creative effects, which of the following would be a better aperture to use?

f22
f1.4

Question 8: A friend shows you a vacation shot of his wife standing in front of a San Francisco cable car. His wife was in focus, but the cable car is not sharp. He had wanted both to be in sharp focus. He most likely could gotten the desired result by:

Focusing on the cable car instead of his wife.
Using a larger diaphragm opening.
Using a different shutter speed.
Using a smaller diaphragm opening.

Question 9: A rangefinder is a device which measures distance from the camera to the subject.

True
False

Question 10: Reading the depth-of-field scale at the setting shown in fig. 17 in your text, you could assume that everything will be acceptably sharp within the distance range of:

4 to 15 feet.
10 feet to infinity.
10 to 25 feet.
7 to 50 feet.

Question 11: Professional motion-picture camera lenses are usually calibrated in T/stops. Any given scene may be shot with several lenses and/or cameras-so it is essential that the exposures match perfectly. This uniformity of exposure between lenses of varying focal lengths and manufacture is possible because the T/stops are calibrated by:

A mathematical formula.
A light transmission test.

Question 12: Why is it necessary to correct for parallax in a viewfinder?

To be sure the viewfinder is parallel with the film.
To ensure getting the same picture on the film as seen in the viewfinder.
To correct for the use of different lenses on the camera.
So the photographer can focus the camera accurately.

Question 13: Why is the problem of parallax eliminated in the single-lens-reflex camera?

Question 14: Will an SLR with a dirty reflex mirror affect the image formed on the film?

Yes
No

Question 15: Fill in the missing words - either "single lens reflex" or "rangefinder type" - to correctly complete the following statements.

In a camera, the viewfinder image always appears in sharp focus.

But in a camera, the viewfinder image appears out of focus until you focus the lens for the proper subject distance.

In a camera, you view the subject through the same lens that takes the picture.

A camera sometimes has interchangeable focusing screens.

A camera, sometimes has framelines which change in the viewfinder when you put on a different lens.

Question 16: A twin-lens-reflex camera can be readily identified because:

It's viewing lens is bigger than it's taking lens.
It has an instant-return reflex mirror.
It's ground glass viewfinder is approximately the same size as the finished negative.
It's viewing and taking lenses focus simultaneously.

Question 17: With the Polaroid SX-70, the print develops:

Inside the camera after the exposure has been made.
Outside the camera after the completed exposure is ejected.
When you pull the film package from the camera.
After you turn the crank to eject the completed exposure.

Question 18: Is it possible to utilize the advantages of Polaroid film on cameras other than those manufactured by Polaroid?

Yes
No

Question 19: The purpose of a press-focus lever is:

To expand or compress the bellows for focusing.
To open the diaphragm leaves for viewing.
To open the shutter blades for viewing.
To turn the focusing ring rapidly.

Question 20: When using a view camera to photograph a tall building you would:

Raise the lens standard.
Tilt the lens standard.
Raise the film back.
Tilt the film back.
