Q

IMPORTANTS CONTROL IN THE CAMERA

A
  1. FOCUSING CONTROL-
  2. FOCUSING RING
  3. SHUTTER SPEED CONTROL
  4. APERTURE OR DIAPHRAGM CONTROL
30
Q

It the means by which the object distance is estimated or calculated to form sharp or clear images

A

FOCUS

31
Q

The adjusting or changing the distance between the focal plane and the length

A

FOCUSING CONTROLLER

32
Q

Type of Focus

A
  1. SCALE BED TYPE or FOCUSING SCALE
  2. MICRO PRISM or RANGE FINDER TYPE
  3. GROUND GLASS TYPE
  4. DEPTH OF FIELD
33
Q

These distances correspond to the distance from the camera to the subject.

A

SCALE BED TYPE or FOCUSING SCALE

34
Q

These are finely etched prism which breaks up the image; they are brought together as you focus.

A

MICRO PRISM

35
Q

Two types of range finder:

A

SPLIT IMAGE and CO-INCIDENT IMAGE

36
Q

Two prism which split your image
in half as you focus both halves re-joins to form a clear image.

A

SPLIT IMAGE

37
Q

This refers to usually to compact a camera that is using a fixed lens.

A

CO-INCIDENT IMAGE

38
Q

The whole of the image on this screen will progressively become
sharp. It is found at the back of the camera or in case of modern,also coupled with the view finder

A

GROUND GLASS TYPE

39
Q

The distance between the nearest object and farthest object that appears to be focus when the lens is focus on infinity. Also called focus range or effective focus range.

A

DEPTH OF FIELD

40
Q

TWO TYPES OF DEPTH OF FIELD (DOF)

A

DEEP DOF and SHALLOW DOF

41
Q

Captures a larger area in focus, often keeping everything in the image sharp and clear.

A

DEEP DOF

42
Q

Refers to a small area in focus. While the background is blurred. This is best for portraits

A

SHALLOW DOF

43
Q

This control is utilized manipulating the ASA/ISO on DIN dial of the camera. Basically, the shutter and the f/number are both controlling the system of the rays of light that enters

A

FILM SPEED CONTROL

44
Q

The view of the subject subtended by two lines emerging the corners of the film extending to the center of the lens.

A

ANGLE OF VIEW

45
Q

It is a device that controls the quantity of light that passes through the lens. It is an iris type mechanism, which shrinks or grows in order to let in less or more lights.

A

APERTURE

46
Q

The smaller the f/number, the larger it is the aperture. Thus, allowing more light reaching the film to compensate for the duration of the shutter curtain travelling time.

A

Aperture Opening

47
Q

FUNCTIONS OF THE APERTURE

A

•As a controller of light
• As a controller of depth of field

48
Q

The time for which the shutter is held open during the taking of photograph to allow light to reach the
film or imaging sensor (in a digital camera). It regulates the amount of time that reaches the film.
It is controlled by the shutter speed dial.

A

SHUTTER SPEED

49
Q

BASIC PRINCIPLES OF SHUTTER SPEED

A

FAST SHUTTER and SLOW SHUTTER

50
Q

It will allow less light to reach the
film

A

FAST SHUTTER

51
Q

It will allow more lights to reach
the film

A

SLOW SHUTTER

52
Q

EFFECTS OF SHUTTER SPEED ON THE PHOTOGRAPH

A

Fast shutter speed and Slow shutter speed

53
Q

Used to freeze motion.

A

FAST SHUTTER SPEED

54
Q

Used to emphasize motion.

A

SLOW SHUTTER SPEED

55
Q

When shooting water in high speed, you can make the water look frozen. It will take a shutter speed of 1/500 or faster to make this magic happen

A

SHOOTING WATER

56
Q

Kinds of Shutter

A

1.Those Placed Before the Lens
2. Those Placed Behind the Lens
3. Between the Lens Shutter
4.Focal Plane Shutter

57
Q

This refers to filter on a box camera usually made of thin metallic disc with an open slot which is made to pass in front of the lens by spring

A

Those Placed Before the Lens

58
Q

This refers to professional or portrait cameras; consist of three metallic leaves which are kept by a spring

A

Those Placed Behind the Lens

59
Q

This refers to a number of metals that overlaps and arranged in a circle; these blades are opened and closed by pins on movable ring

A

Between the Lens Shutter

60
Q

This refers to light tight overlapping curtains containing a narrow slit which passes across the focal plane in front of the film. Driven by a spring, this window moves across the film as it moves. The amount of light is controlled by the speed of the curtain and the width of the slit. The amount itself - Just in front of the lens of the film, of focal plane rather than the lens

A

Focal Plane Shutter

61
Q

Characteristics of Subjects;

A
  1. Brilliant
  2. Bright
  3. Average
  4. Shaded
62
Q

This refers to beach, marine and snow scenes; landscapes and mountains without prominent dark object in the foreground

A

BRILLIANT

63
Q

This refers to people in marine, beach or snow scenes with foreground objects

A

BRIGHT

64
Q

This refers to nearby people, gardens, houses and scenes not in shades.

A

AVERAGE

65
Q

This refers to subjects in the open

A

SHADED

66
Q

This refers to length of time needed by the light ray to reach and affect the film inside the camera that is restricted by the shutter speed control of the camera.

A

SHUTTER SPEED CONTROL
