The relationship between focal length and angle of view is such that the shorter the focal length the:

wider the angle of view

narrower the angle of view

sharper the image

larger the image will appear on the film
wider the angle of view
pg.46
A technique that is used to maintain sharp focus on a subject that is moving toward you is called:

manual focus

automatic focus

zone focus

follow focus
follow focus
pg. 50
A wide-area focus system is an automatic focusing system that allows the photographer to:

choose the area that will be in focus

shoot with a wide angle lens

shoot at fast shutter speeds

manually set exposures
choose the area that will be in focus
pg. 52
The relative aperture is equal to the lens focal length divided by the:

pg. 56
Which of the following is not likely to affect the depth of field?

the aperture

the shutter speed

the focal length of the lens

the distance the photographer is from the subject

pg. 57
A useful focusing technique to use when you want to shoot rapidly in a situation in which you can predict the approximately where, if not exactly when, action will take place is called:

Focusing on the hyperfocal distance

Zone focusing

parallax

perspective control
Zone focusing
pg. 58
The relationship between focal length and magnification is such that the longer the focal length the:

wider the angle of view

greater the magnification

less the magnification

greater the depth of field
greater the magnification
pg. 40
When buying a lens, it is a good idea to buy a lens shade that:

is two times the focal length of your lens

matches the focal length of the lens

matches the color of your camera

Most digital SLRs have a normal lens that is a shorter focal length than that of 35mm SLR film cameras. This is because______.

a digital camera body is smaller than a film camera.

the sensor is smaller than a frame of 35mm film.

the depth of field is greater at any given aperture.

they have a narrower angle of view than lenses used with film cameras.
the sensor is smaller than a frame of 35mm film.
pg. 57

pg. 59
______________ are the three main factors that affect depth of field.


The aperture, the amount of light in the scene, and the size of the subject

The size of the sensor, the aperture, and the lens's focal length

The aperture, the lens's focal length, and the distance from the subject

The distance from the subject, the aperture, and the f-stop
The aperture, the lens's focal length, and the distance from the subject
pg. 57
T or F: A lens with a longer focal length will produce a larger image on the film.
True
pg. 40
T or F: Provided that the subject remains at the same distance from the lens, the image formed by a 50mm lens will be half the size of that formed by a 25mm lens.
False
pg. 40
T or F: Longer lenses are good for portraiture because they have less distortion.
True
pg. 44
T or F: You should clean your camera's digital sensor monthly.
False
pg. 63
T or F: A camera's autofocus system can be fooled into focusing incorrectly by objects in front of your intended focal point.
True
pg. 52
T or F: The single-shot autofocus mechanism prevents the photographer from taking a picture unless it is in focus. This is also called focus priority.
True
pg. 52
T or F: The larger the circle of confusion, the less likely it is that the subject will appear out of focus.
False
pg. 54
T or F: A smaller aperture will increase depth of field.
True
pg. 56
T or F: Depth of field will be greater with a 50mm lens than with a 180mm lens.
True
pg. 57
T or F: A long-focal-length lens is best used when zone focusing.
False
pg. 58
T or F: Depth of field extends two-thirds in front of the plane of critical focus and one-third behind it.
False
pg. 61
T or F: The lens of a longer focal length produces less depth of field than a shorter lens used at the same f-stop.
True
pg. 56
