Chap 3 Flashcards
-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
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 simple camera that is little more than a pinhole camera,
the pinhole is replaced by the lens to enable the photographer gather lighter to be
recorded
Box Camera (brownie)
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
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
It uses a mirror that reflects an image of the scene upward onto a viewing screen.
Its problem is parallax error.
Twin lens reflex camera
This camera literally allow anyone to capture beautiful images by simplifying pointing the camera at the subject and clicking the shutter.
Compact camera/ point and shoot camera
This cameras take photos to the next level of image quality. This more “serious” type of camera is best known for delivering
remarkably sharp and spectacular images.
DSLR( digital single lens reflex)
They are
basically more compact DSLRs without the internal mirror that reflects light onto the
sensor
Mirrorles cameras
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 cameras
Other types of cameras
-Instant cameras
-Film cameras
-Smartphone cameras
Four Important Controls in the Camera
- Focusing Control
- Focusing Ring
- Aperture or Diaphragm Control
- Shutter Speed Control
Parts of camera
- Shutter
- Lens
- Focusing ring
- Diaphragm or aperture
- Film advance lever
- Shutter speed dial
- Shutter release button
- View finder
- Self time
- Film holder
- Flash terminal
A disc of transparent glass generally bounded by two special surfaces capable of forming an image.
- eye for the camera
Lens
An adjustable mechanism that regulates the amount of light reaching the film
by varying the length of time. This is a control by which you can determine how long in
time the lens will remain open for light to be recorded on the film.
Shutter
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
The type of focus is that the 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
