LIGHTING SYSTEMS THAT AFFECT PHOTO-TAKING

A

Haze (Mist of Fog)
Direction of Light
Frontal lighting
Side lighting

36
Q

The particles in the air act as filter, rendering objects very soft in an image except for those in the foreground. The farther away from the camera, the more that detail seems to merge and dissolve into the background

A

Haze (Mist of Fog)

37
Q

Light that falls on your subject is very important. Obviously, you can’t move the sun, but you can move your subject or your camera position to get the desired effect. You can also choose the time of day to best illuminate your subject.

A

Direction of Light

38
Q

strikes the surface of the subject straight-on. The sun (or other light source) is behind the camera and the floods the scene evenly with light.

A

Frontal lightning

39
Q

Frontal lightning is easy to work with, but often yields unsatisfactory results. If you are photographing a person, the shadows will be cast behind your subject, creating your photo often ___________ and colors may be _________.

A

lack depth and colors may be washed out

40
Q

Occurs when the light source skims across the surface of the subject facing your lens, which emphasizes texture and shape. This lightning is great for landscapes, weathered buildings, and other situations in which you want to reveal texture and depth in your images. Backlighting.

A

Side-lighting (Slide-lighting)

41
Q

When light strikes a surface and rebounds. It is called incident light.

A

REFLECTION

42
Q

The angle at which reflected light strikes.

A

Incident angle

43
Q

KINDS OF REFLECTION

A
  1. Specular
  2. Defuse
44
Q

If the surface is smooth and polished that the reflected rays are not scattered.

A

SPECULAR REFLECTION

45
Q

When reflected light is scattered by a rough surface. A reflected wave always comes off the surface of a material at an angle equal to the angle at which the incoming wave hit the surface.

A

DIFFUSE REFLECTION

46
Q

“The angle of incidence equals the angle of reflection”. In physics, this is called the __________.

A

Law of Reflectance

47
Q

Light rays may be allowed to pass through some media they encounter.

A

TRANSMISSION

48
Q

When light falls upon an object and is neither transmitted nor reflected, it is absorbed. It makes an object dark or opaque to the frequency of the incoming wave.

A

ABSORPTION

49
Q

A ray of light which passes obliquely from a medium such as air through a substance of different density is bent.

A

REFRACTION

50
Q

It is called refracted image. It happens when air near the ground is much hotter than air higher up.

A

MIRAGE

51
Q

▪︎ A light in space and not within the gravitational field of any object travels in a straight line. The bending of light around as object.

▪︎ This phenomenon is responsible for the partial illumination of object parts not directly in the path of the light.

A

DIFFRACTION

52
Q

KINDS OF MATERIALS:

A

a. TRANSPARENT
b. TRANSLUCENT
c. OPAQUE

53
Q

If the object permits light to pass through it, as a clear pane of glass or lens.

A

TRANSPARENT

54
Q

If an object scatters light to pass through it.

A

TRANSLUCENT

55
Q

An object that does not permit light to pass through it.

A

OPAQUE

56
Q

TYPES OF ACCESSORY FLASH UNITS

A
  1. Manual Flash
  2. Automatic Flash
  3. Dedicated light unit
  4. Built-in Flash
  5. Off camera Flash
  6. Flash Synchronization Speed
57
Q

These flash units require you to figure out the correct exposure for your shooting conditions.

A

Manual Flash

58
Q

These flash units use automatic sensors to control light output and duration based on the distance from the camera to the subject. When you set the aperture you want to use, the flash will automatically calculate how much light is needed to illuminate a specific distance range, such as 3 to 15 feet; the flash unit will have an electric eye that reads the amount of light bouncing back from the subject.

A

Automatic Flash

59
Q

They are made to work with your camera in specific electronic means (hence the name). They will do all the thinking for the photographer: automatically setting the correct shutter speed and aperture, and controlling the exposure by regulating flash duration.

A

Dedicated Light Unit

60
Q

67
Q

Camera that fold into a compact and rugged package for storage. The lens and shutter are attached to a lens-board which is connected to the body of the camera by a light-tight folding bellows. When the camera is fully unfolded it provides the correct focus distance from the film.

A

Folding Camera

68
Q

Were the first cameras to have an optical viewfinder-that is, a separate, window-like lens through which the photographer sees and frames the subject. The viewfinder is paired with an adjacent window.
