Chapter 3 Additional Flashcards
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, the image being projected on the film at the other
end.
Pinhole camera
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.
Camera obscura
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 mechanical device that is used to form and record the rays of light (as reflected by the object) on the film inside the light tight box.
CAMERA
The camera lens is incorporated into the bellows which is slid back and forth along a rail to change focus. There is a cloth covering.
Folding camera
cameras like GoPro can fit of your hand, but they’re some of the most durable and versatile types of digital cameras that offer very highresolution output.
Action camera
Other types of camera
-Instant cameras
-Film cameras
-Smartphone cameras
Four Important Controls in the Camera
Focusing Ring
Focusing Control
Aperture or Diaphragm Control
Shutter Speed Control
Parts of camera
Shutter
Shutter speed dial
Shutter release button
Self time
Lens
Film holder
Flash terminal
Focusing ring
Film advance lever
Diaphragm or aperture
View finder
This refers to a tripled leg device which is adjustable to any reasonable
extension. This can be used in holding the camera
Tripod
This refers to camera accessories that is attached to the shutter release of the camera and used in releasing and closing the shutter to prevent accidental movement of the camera during the exposure period especially when longer exposure is
made.
Cable release
This refers to flash bulbs or electric flash which synchronizes with the
opening and closing of shutter. This is very effective to augment the adverse lighting condition of the object(s) being photographed.
Flash units
This refers to a device used in determining the intensity of light that strike the subject and affect the film inside the camera.
Light meter
This refers to a transparent medium which transmits and absorbs different wavelength of lights usually made of glass or gelatine material placed in front of the camera lens
Filter
These are finely etched prisms which break up the image; they are brought together as you focus.
Micro prism type
these distances correspond to the distance from the camera to the subject
Scale bed type
This refers to two prisms that splits the image in half as you focus both
halves re-joins to form a clear image
Split image
This refers to usually to compact a camera that is using a fixed lens
Co incident image
It is a matt glass. The whole of the image on this screen will progressively become sharp.
Ground glass type
this control is utilized by manipulating the ASA/ISO or DIN dial
of the camera. Basically, the shutter and the f/numbers are both
controlling the system of the rays of light that enters.
Film speed control
overlapping circle patches of light representing each patch of
light on the subject
Circle of confusion
this is the nearest distance at which a lens is focused with a given particular diaphragm opening which will give the maximum depth of field.
Hyperfocal distance
Characteristics of subject that refers to beach, marine and snow scenes; landscapes and mountains without prominent dark object in the foreground.
Brilliant
Characteristics of subject that refers to people in marine, beach or snow scenes with foreground objects.
Bright
Characteristic of subject that refers to nearby people, gardens, houses and scenes not in shades
Average
This refers to subjects in the open (not under trees, porch, roof,
etc.).
Shaded
Kinds of Shutter
-those placed before the lens
- those placed behind the lens
-blade or between the lens shutter
- focal plane shutter
This refers to a device used in photographing a minute object.
It is attached to the lens board of the camera and the lens is attached to it when close – up photography is necessary.
Extension tube
This refers to a device used to hold firmly the camera so as to prevent the vibration or movement of the camera during the exposure period.
It is attached to the body of the camera and sometimes
the flash unit is attached to it.
Camera grip
This refers to a device used to eliminate some reflections of light which might destroy the
image cast of the object(s) especially when the light is coming from the top or side position of the camera.
It is usually mounted in front of the lens barrel
Lens hood
This refers to long lenses having less depth than short lenses.
Focal Length of the Lens
This refers to the depth of field that is directly proportional to distance
Distance from the camera to object
