25
what kind of photo does smaller aperture produce
larger depth of field, everything will be sharper
26
what number of f stop does a small aperture have?
large f stop
27
depth of field
area from near to far in a scene that is accepably sharp in a photograph
28
what 3 facts effect depth of field
aperture, focal distance, and shooting distance
29
minimal depth of field
small amount of image in focus
30
how does a larger opening effect lighting
more light
31
how does a smaller opening effect lighting
less light
32
shutter speed
controls the amount of light that reaches the sensor by the length of time the shutter remains open.
33
fast shutter
less light, darker
34
slow shutter
more light, light
35
shutter speed and aesthetics
capturing and blurring emotion
36
what does the lens do?
Moves forward and backward to bring objects at different distances to focus
37
Viewfinder
shows picture
38
sensor
converts light to electrons signals
39
ISO speed
describes a sensors sensitivity to light, higher the number the less light is needed for correct exposure
40
ISO for sunny conditions
50-800
41
ISO for indoor conditions
800+
42
What is resolution also know as
Image quality
43
What does a lower resolution allow you to do
Store more images on memory card but with loss of quality
44
Raw format photos
highest resolution, keeps the quality the highest
45
Higher numbers in ISO speed
lets you shoot in lower light but produces images with more noise
46
White balance aka
color temperature
47
white balance
dominate light source of what you are photographing
48
how to correctly expose a photo
must set shutter speed and aperture according to ISO sensitivity and how dark/ light the subject is
49
Exposer: shutter speed
determines the length of time that light strikes sensor
50
Exposure: aperture size
determines how bright the light that passes is that passes through lens
51
How can you see you image in SLR
directly through the lens
52
Rangefinder cameras
have viewfinder
53
parallax error
viewfinder and lens don't see exactly the same thing
54
Twin lens reflex camera (TLR)
Two lens, one for viewing and other for exposing film
55
Mirrorless cameras
have small monitor that displays what the lens is seeing aka live view
56
resolution
maximum number of pixels a camera sensor can capture
57
sensor size
The larger and less crowded the light sensing elements are in the sensor the higher quality of the image
58
How to focus camera
by turning ring on the lens or auto focus
59
what does shutter speed affect
light and motion
60
Automatic exposure (A)
camera built in meter measures brightness of the scene and sets shutter speed or aperture
61
Program fully automatic exposure (P)
camera sets both shutter speed and aperture
62
Shutter Priority (TV)
You set shutter speed and camera auto sets aperture
63
Aperture priority (AV)
You set aperture and camera auto sets shutter speed
64
Manual (M)
You set both shutter speed and aperture
65
slow shutter speed
objects blurred
66
fast shutter speed
objects sharp
67
panning camera
shows blur in background but not on moving subject
68
what does aperture effect?
light and depth of field
69
bigger the aperture hole
the smaller the f-stop numbers
70
what does aperture do to depth of field
as aperture gets smaller, depth of field increases, more of the scene from near to far appears sharper
71
more depth of field (Ape)
small aperture
72
Less depth of field (Ape)
large aperture
73
lens speed
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
74
single/ fixed focal length AKA
prime lens
75
what focal length is most like human Vision
normal focal length
76
long focal length, what is shown
less of scene, and what is shown is magnified
77
shorter lens (DOF)
more DOF
78
longer lens (DOF)
little DOF
79
3 factors that effect DOF
aperture size, focal length, and lens to subject distance
