Q

shutter speed

A

controls the amount of light that reaches the sensor by the length of time the shutter remains open.

33
Q

fast shutter

A

less light, darker

34
Q

slow shutter

A

more light, light

35
Q

shutter speed and aesthetics

A

capturing and blurring emotion

36
Q

what does the lens do?

A

Moves forward and backward to bring objects at different distances to focus

37
Q

Viewfinder

A

shows picture

38
Q

sensor

A

converts light to electrons signals

39
Q

ISO speed

A

describes a sensors sensitivity to light, higher the number the less light is needed for correct exposure

40
Q

ISO for sunny conditions

A

50-800

41
Q

ISO for indoor conditions

A

800+

42
Q

What is resolution also know as

A

Image quality

43
Q

What does a lower resolution allow you to do

A

Store more images on memory card but with loss of quality

44
Q

Raw format photos

A

highest resolution, keeps the quality the highest

45
Q

Higher numbers in ISO speed

A

lets you shoot in lower light but produces images with more noise

46
Q

White balance aka

A

color temperature

47
Q

white balance

A

dominate light source of what you are photographing

48
Q

how to correctly expose a photo

A

must set shutter speed and aperture according to ISO sensitivity and how dark/ light the subject is

49
Q

Exposer: shutter speed

A

determines the length of time that light strikes sensor

50
Q

Exposure: aperture size

A

determines how bright the light that passes is that passes through lens

51
Q

How can you see you image in SLR

A

directly through the lens

52
Q

Rangefinder cameras

A

have viewfinder

53
Q

parallax error

A

viewfinder and lens don’t see exactly the same thing

54
Q

Twin lens reflex camera (TLR)

A

Two lens, one for viewing and other for exposing film

55
Q

Mirrorless cameras

A

have small monitor that displays what the lens is seeing aka live view

56
Q

resolution

A

maximum number of pixels a camera sensor can capture

57
Q

sensor size

A

The larger and less crowded the light sensing elements are in the sensor the higher quality of the image

58
Q

How to focus camera

A

by turning ring on the lens or auto focus

59
Q

what does shutter speed affect

A

light and motion

60
Q

Automatic exposure (A)

A

camera built in meter measures brightness of the scene and sets shutter speed or aperture

61
Q

Program fully automatic exposure (P)

A

camera sets both shutter speed and aperture

62
Q

Shutter Priority (TV)

A

You set shutter speed and camera auto sets aperture

63
Q

Aperture priority (AV)

A

You set aperture and camera auto sets shutter speed

64
Q

Manual (M)

A

You set both shutter speed and aperture

65
Q

slow shutter speed

A

objects blurred

66
Q

fast shutter speed

A

objects sharp

67
Q

panning camera

A

shows blur in background but not on moving subject

68
Q

what does aperture effect?

A

light and depth of field

69
Q

bigger the aperture hole

A

the smaller the f-stop numbers

70
Q

what does aperture do to depth of field

A

as aperture gets smaller, depth of field increases, more of the scene from near to far appears sharper

71
Q

more depth of field (Ape)

A

small aperture

72
Q

Less depth of field (Ape)

A

large aperture

73
Q

lens speed

A

maximum aperture, widest aperture to which lens diaphragm can be opened. A lens that is faster opens to a wider aperture and admits more light
