Camera components
The camera usually consists of a light-tight box (camera body), lens system, the lighter portrait (shutter), and other parts.
1. Camera body
Camera body is a light-tight room, but connected with a lens which is where the only light inside. Here, the light focused by the lens will be set to the right about and burn movies.
Cameras used for photography are usually performed jointly added several control buttons, among others:
- Regulator ISO / ASA film;
- Shutter Speed;
- Aperture (aperture diaphragm).
In addition, there are other additional equipment.
- Flash
- Tripod
- Lightmeter
2. lens system
Lens system is mounted on the front of the pit box in the form of a single lens made of plastic or glass, as well as a number of lenses in a metal cylinder. Light blockage level is denoted with the letter f (relative aperture). If the openings are relatively lower, the greater the smaller the opening or penghalangannya level. Aperture diaphragm is set by the window. SLR camera lenses are usually equipped with a regulator aperture diaphragm to adjust the amount of light entering the photographer as you wish.
3. lighters Portrait
Shutter or button mounted on the back of the lighters portrait lens or between the lenses. Most SLR cameras have a timer mechanism to vary the shutter opening time.
4. Other sections
In addition to these three components, there are also other additional components. Additional components of the camera are as follows.
- Mechanisms play the movie rolls that make parts of the movie alternately be exposed on the object.
- Focal mechanism for varying the distance between the lens and film.
- Range finder or a scanner composition that serves photography shows what will be photographed, and whether the main object will be focused.
- Lighmeter who helped set shutter speed to produce a perfect picture.
Type of Camera Based on Light Catchers Media
1. movie camera
The camera uses a celluloid film. In this band there is silver halide grains are very sensitive to light. At the time of the washing process the film, silver halide is exposed to light with the right size, will go black. Meanwhile, the silver halide that size is not appropriate, will be dissolved with the liquid developer (developer).
The types of films based on the size are as follows.
- Small format (35mm)
- Medium format (100-120mm)
- Large format
The types of films based on the material and the sensitivity is as follows.
- Black and white film
- color film
- positive film
- film negative
- daylight film
- tungsten film
- Film infrared (heat-sensitive surface that reflected object)
2. Digital cameras
The digital camera is a tool to create images of objects and refracted through the lens to the CCD sensor. After that, the results are recorded into a digital media store. Digital camera works without using film.
To manangkap an object, the photographer can easily be aimed at him without using a window view. LCD screens mounted in the rear view camera is a replacement window. This camera uses iternal memory or external memory using memory cards as storage media.

Digital cameras are categorized in two types, namely:
- Digital pocket camera (digital pocket camera);
- Digital camera SLR (Single Lens Reflect Digital Camera).

Video camera.
Still camera (for capturing still images).
Webcams (digital camera connected to a computer and used for video teleconferencing and other purposes).
