CHAPTER 2 ( ESSENTIAL PARTS OF CAMERA ...) Flashcards
ESSENTIAL PARTS OF A CAMERA
1) BODY/ LIGHT TIGHT BOX
2) LENS
3) FILM HOLDER
4) SHUTTER
5) VIEW FINDER
6) FILM ADVANCER & LEVER
7) SHUTTER SPEED
8) LENS APERTURE
9) FOCUSING MECHANISM
Part of the camera that is very important because of its capability to exclude all the unwanted light that might expose the film.
Light Tight Box or Body
The lens is the image forming device on a camera, a glass, plastic, or crystal optical element molded into a curved shape that can bend and focus rays of light; responsible for focusing the rays of light coming from the subject
Lens or Pinhole
Holds the film firmly inside the camera
Film Holder
Device used to control the amount of time during which light is allowed to enter the camera and register on the film or image sensor; serves as the barrier of the rays of light that will enter and affect the film inside the camera
Shutter
An optical or electrical device used to compose and frame a scene; shows the entire scene coverage that can be recorded in the film inside the camera; also called a view system, a finder or a viewing screen.
Viewfinder or Viewing System
A mechanism for moving film from one spool to another incrementally one frame at a time.
Film Advancer & Lever
It will control the duration between the opening and closing of the shutter.
Shutter Speed
An opening (diaphragm) in a light-blocking plate that allows light to strike the film or image sensor; the ratio between the diameter and focal length of the lens; the light gathering power of the lens.
Lens Aperture
The sharpness or clearness of the objects being photographed will depend upon the focusing system of the camera.
Focusing Mechanism
The physical point at which rays of light from a lens converge to form a properly defined image of the subject.
Focus
When pressed, this button manually lifts the mirror inside the camera. This is useful for minimizing camera shake, which can use out-of-focus image during high magnification photography.
Mirror Lock-up Button
A button either on the camera or on the lens which turns the auto-focus feature on and off.
Auto focus/Manual Focus Button
Is the abbreviation for the International Standards Organization. In the “old days” this was called the ASA or American Standards Association
ISO/ASA Button or Dial
To remove the lens from the body on most new cameras, press in this button and twist the lens to unlatch it. On some older cameras, the lens is literally unscrewed from the body. If you are having problems focusing with auto- focus cameras and lenses, check to make sure the lens is tightly fastened to the camera body
Lens Release Button
Press this button to “freeze” the exposure setting on the meter. This is useful if your composition places the neutral-toned object away from the metering points. Meter the subject, look the exposure and recompose, and take the picture.
Exposure Lock Button
This automatically advance the film after the exposure is finished. Older cameras have located near the thumb when the finger is on the shutter release. Pulling this out turns on the meter. Ratcheting this out and to the right advances the film and readies the camera for the next shot
Manual Advance Lever
This button will set the camera to take a picture 2 to 20 seconds after you press the shutter. This is the feature your use to put yourself in the photograph. It’s also useful if you have forgotten or lost the cable release.
Self Timer
All look different on different cameras, some cameras have a switch which slides, twists or swings. Some older camera turn on their meters (that means the camera is on the power is draining from the battery) When the film advance lever is pulled out. Some camera requires two moves instead of one to turn it on; push in and turn at the same time
Off/On Button
Controls the opening and closing of the shutter; regulates quantity of light that reaches and effects the film inside the camera; a dial which sets the length of time in which the light is allowed to enter the camera
SHUTTER SPEED DIAL - (SSD)
The click of the camera which releases the shutter.
SHUTTER RELEASE BUTTON
The mechanism that estimates the appropriate objects distance from the camera to form a sharp or clear image the photograph
FOCUSING MECHANISM
The outer ring of the lens which is rotated or adjusted to obtain a clear and sharp photograph enables the photographer to adjust focal range.
Focusing the ring
The focus index or range of sharp focus, a set of number which determines the appropriate depth of field.
Distance Scale
The window to control how much light reaches the film, the mechanical device in the focusing assembly that is used by the photographer to adjust in the aperture.
DIAPHRAGM
Refers to the diameter (size) of the camera lens opening. It is manifested by the F- stop step in the diaphragm ring.
APERTURE
Film speed indicator
ASA DIAL/FILM SPEED DIAL
