A

DIAPHRAGM OR APERTURE

17
Q

A part of the camera that is TWISTED TO ADVANCE THE FILM inside and to check the number of exposure.

A

FILM ADVANCE LEVER

17
Q

It will CONTROL THE LENGTH OF TIME when light is allowed to strike the sensitized material.

A

SHUTTER SPEED DIAL

17
Q

A VIEWING INSTRUMENT attached to a camera, used to obtain proper composition.

A

VIEW FINDER/WINDOW

17
Q

The TIME SETTING OF A CAMERA- this is automatically operated allow the photographer to participate in photo-taking.

A

19
Q

It is where FLASH BULB CORD is plugged for synchronization to the camera.

A

FLASH TERMINAL

20
Q

FOUR IMPORTANT CONTROLS IN THE CAMERA:

A
  1. FOCUSING CONTROL
  2. FOCUSING RING
  3. SHUTTER SPEED CONTROL
  4. APERTURE OR DIAPHRAGM CONTROL
21
Q

A LARGE KNURLED RING around the barrel of this lens, when turned the lens will either move away or toward the camera body, depending upon the direction of rotation until ring cannot be turned further. At this stopping point, all distant objects are in focus regarding of difference in their distance, is termed infinity focus or simply infinity.195

A

FOCUSING RING

21
Q

It the means by which the object distance is estimated or CALCULATED TO FORM SHARP or clear images.

A

Focus

21
Q

The ADJUSTING OR CHANGING THE DISTANCE between the focal plane and the length

A

Focusing

21
Q

TYPES OF FOCUS:

A

MICRO PRISM
SPLIT IMAGE

22
Q

These are finely etched prisms which BREAK UP THE IMAGE; they are brought together as you focus.

A

MICRO PRISM

22
Q

two prism which splits your image in HALF AS YOU FOCUS both halves rejoins to form a clear image.

A

Split image

23
Q

It is FOUND AT THE BACK OF CAMERA or in the case of modern, also coupled with the view finder.

A

GROUND GLASS TYPE

23
Q

A ground glass is a MATT GLASS. The whole of the image on this screen will progressively become sharp.

A

GROUND GLASS TYPE

23
Q

The point of focus is where the IMAGE IS SHARPEST

A

GROUND GLASS TYPE

23
Q

The distance between the NEAREST OBJECT AND FAREST OBJECT that appears to be focus when the lens is focus on infinity.

A

DEPTH OF FIELD

23
Q

also called FOCUS RANGE or effective focus range.

A

DEPTH OF FIELD

23
Q

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

A

FILM SPEED CONTROL

23
Q

The view of the subject subtended by TWO LINES EMERGING the corners of the fill extending to the center of the lens.

A

ANGLE OF VIEW

23
Q

It regulates the AMOUNT OF TIME that reaches the film. It is controlled by the shutter speed dial.

A

Shutter Speed

23
Q

is the TIME FOR WHICH THE SHUTTER is held open during the taking of a photograph to allow light to reach the film or imaging sensor (in a digital camera).

A

Shutter Speed

23
Q

Basic Principles of Shutter Speed:

A

Fast Shutter
Slow Shutter

23
Q

speed will allow MORE LIGHT to reach the film.

A

Slow Shutter

23
Q

speed will allow LESS LIGHT to reach the film.

A

Fast Shutter

24
Q

A photo at night with automatic EXPOSURE TIME 1/8 SEC

A

Fast Shutter

25
Q

The same photo on the left taken with EXPOSURE TIME 10 SEC

A

Slow Shutter

26
Q

It is a LIGHT TIGHT BOX chambered to the aperture enclosed in a shutter at the opposite end of which is the place where the sensitized material is located

A

Camera

27
Q

Early forms of camera:

A

Pinhole camera
Box camera
Camera obscura
Folding camera
Twin lens reflex camera

28
Q

This refers to a SIMPLE DESIGN AND CONSTRUCTION, usually home-made consisting of a box having a small aperture functioning as a lens at one end

A

Pinhole camera

29
Q

This refers to a SIMPLE CAMRRA THAT IS LITTLE MORE than a pinhole camera

A

Box camera

30
Q

This refers to a DARKENED CHAMBER OR SMALL BUILDING in which images of outside objects are projected onto a flat surface by a convex lens in aperture
