Quiz 1

Select the five important factors controlling the appearance of motion in your images.

Shutter speed, subject direction, subject velocity, focal length, distance

Which description that best describes the functionality of the "B" shutter speed option?

The B (or bulb) setting is a manual shutter speed as it keeps the shutter open as long as the shutter release is held down.

Changing the focal length of the lens alone will not change the apparent perspective in a photograph but lens AND distance will.

True

Having your subject move across the film plane (from one side to the other) will be more likely produce motion blur than having the subject move towards the camera.

True

True or False? 1/60 lets in twice as much light as 1/125, and half as 1/30?

True

When shooting with a long focal length lens the apparent perspective (how close together objects look to one another in a photograph) will appear to be ____________.

compressed

If the correct exposure for a scene was f/8 at 1/30 of a second, select all the correct reciprocal exposures using the table provided above. *You must select ALL correct answers to receive credit.

f/4 @ 1/125, f/16 @ 1/8, f/5.6 @ 1/60

Which distance change would increase the amount of motion blur in your photograph?

moving closer

Depth of Field extends about _____ in front of and _____ behind the plane of critical focus

1/3 in front of and 2/3

List the missing speed setting of these commonly found shutter speeds: 1, 2, 4, 8, ___ , 30, 60, 125, 250, 500, 1000. *Make sure to enter the exact numeric value only.

15

Which aperture setting would give you the greatest amount of depth of field, f/22, f/11, or f/5.6? *Make sure to NOT include f/ when answering; just indicate the numeric value after f/___.

22

Which shutter speed would produce less blur if you were photographing a running person, 1/4 or 1/250? *Make sure to NOT include 1/ when answering; just indicate the numeric value after 1/___.

250

Which focal length would give you the least amount of motion blur in your photograph, 28mm, 50mm, or 80mm? *Make sure to NOT include "mm" when answering; just indicate the numeric value before mm.

28

If a 50mm lens gives you a normal angel of view when shooting with a full-frame sensor or 35mm film, list the focal length number for a lens that will give you a wide angle of view when using the same camera. *Make sure to enter a numeric value only for a commonly used wide angle (short) lens.

35

List the missing aperture setting of these commonly found f-stop numbers: 2, 2.8, 4, 5.6, ____ , 11, 16. *Make sure to enter the exact numeric value only.

8

If a 50mm lens gives you a normal angel of view when shooting with a full-frame sensor or 35mm film, choose the number that best represents a lens size that will give you a more narrow angle of view when using the same camera.

80

Which focal length would give you the least amount of depth of field, 28mm, 50mm, or 80mm? *Make sure to NOT include "mm" when answering; just indicate the numeric value before mm.

80

The focal length of the lens controls what two things?

Angle of view, apparent perspective

The aperture or f-stop controls what two things?

Depth of field, exposure

The shutter speed setting controls what two things?

Exposure, motion blur

True or False? The longer the focal length of the lens, the wider the angle of view; the shorter the focal length of the lens, the narrower the angle of view

False

True or False? f/8 lets in twice as much light as f5.6, and half as f/11?

False

Select the four important factors controlling the amount of depth of field in your images.

Focal length, distance, aperture, focus point

Which distance change would increase the amount of depth of field in your photograph?

Moving farther away
