Q

Why do we photograph in RAW?

A

they are uncompressed, bigger image files with more information, and are unedited by the camera

Q

How is setting the camera’s white balance important when photographing partially in color?

A

it will balance the blues and greens, make sure the colors are correct; fixes the temperature of light

21
Q

What is an appropriate shutter speed for hand-holding?

A

1/60 or ABOVE

22
Q

Focal Length

A

the distance between the optical center of your lens and the sensor of the film plane

23
Q

Focal Length measured in

A

mm

24
Q

Normal focal length for a DSLR

A

50-55mm

25
Q

Wide angle lens on a DSLR

A

Anything less than 50mm

26
Q

Long angle lens on a DSLR

A

Anything more than 55mm

27
Q

Angle of View

A

how much of the scene you can see

28
Q

What is the human angle of view?

A

47 degrees

29
Q

The angle of View in relation to Focal Length?

A

Wide angle shows more of an angle of view

30
Q

How does Focal Length relate to Depth of Field?

A

The longer the lens, the less DOF you get at any aperture

31
Q

ISO

A

the numerical value given to the sensor or film’s SENSITIVITY to light

32
Q

Which is considered a slower ISO? 125 or 400

A

125

33
Q

Lower # (ISO)

A

Slower ISO and needs more light

34
Q

Which ISO would need less light for an exposure? ISO 800 or 400?

A

ISO 800

35
Q

High # (ISO)

A

Faster, less light needed

36
Q

What is the benefit of using a faster ISO?

A

Will make images brighter, good for lower light, may not need to use a tripod

37
Q

Cons of faster ISOs

A

Grainy

38
Q

Benefits to using a slower ISO

A

it is less sensitive to light so you will have sharper images, allows for longer shutter speed

39
Q

Cons for slower ISOs

A

Need more light or a tripod

40
Q

3 Things that control Depth of Field?

A

Aperture
Focal Length
Length from Subject (Camera to Subject)

41
Q

The range of focus that exists in front of the sharpest plane of focus and behind the sharpest plane of focus is based on what ratio?

A

1/3 in front, 2/3 in back (or 1/3:2/3)

42
Q

Critical plane of focus?

A

what is your SUBJECT

43
Q

When you are close to your subject, how does that affect Depth of Field at any given aperture?

A

it will make your depth of field shallow; less DOF

44
Q

If you are shooting with a wide angle lens, how does that affect the Depth of Field?

A

you will have a longer DOF

45
Q

If you want to overexpose your film ONE stop from F5.6 @ 1/60, what F-stop/shutter speed setting could you use?

A

F4 @ 1/60 OR F5.6 @ 1/30

46
Q

If you want to underexpose your film ONE stop from F5.6 @ 1/60, what F-stop/shutter speed setting could you use?

A

F8 @ 1/60 OR F5.6 @ 1/125

47
Q

What does it mean to BRACKET your exposures?

A

Purposely under AND over exposing your image

48
Q

What is exposure equivalent?

A

using the same total volume of light but using different settings to do so

49
Q

Exposure equivalent for F8 @ 1/60

A

F11 @ 1/30, F16 @ 1/15, F5.6 @ 1/125

50
Q

Exposure equivalent for F5.6 @ 10”

A

F4 @ 5” OR F11 @ 40”
