The camera is the most important tool in the world and photography activities. The name is derived from camera obscura, Latin for “dark room”, the early mechanisms for projecting a view where one room serves as the workings of a modern photographic camera, except there is no way at that time to record the show other than manual drawing on his trail. In the world of photography, the camera is a device to establish and record an image of the portrait on the film sheet. In the television cameras, the lens system forming an image on a light sensitive plate. This plate will emit electrons into the target plate when exposed to light. Furthermore, the electron beam is treated electronically. Known to many types of portrait camera.

Camera components

A general camera consists of:

1. Light-proof box (camera body)
2. Lens System
3. Trigger (shutter)
4. Film roll

Camera film

Type of film cameras used are of 35 millimeters, which became popular because usefull and speed when taking pictures, because this camera is small, compact and unobtrusive. Sometimes interchangeable lenses, and cameras that can load the roll of film for 36 outcrop, sometimes even more.

Type film

The division of the film based on size:

1. Small format (35mm)
2. Medium format (100-120mm)
3. Large format

Numbers above the diagonal size of the film is used. Each type of emotion the film sizes using different cameras.

The division of the film based on the type of materials:

• Black and white film
• Film Positive
• Negative Film
• Film daylight
• Film tungsten
• Film infrared (heat sensitive surface of the reflected object)

Polaroid cameras

This type of camera using Polaroid sheet which gives a direct positive image so that the photographer does not need to do the washing process of the film print.

Digital Camera

This type of camera is a camera that can work without using film. The photographer can easily grasp an object without having to bother to aim through the window of view because most digital cameras do not have it. Instead, a digital camera using an LCD screen mounted on the back of the camera. LCD screen on every digital camera is different. For storage, digital cameras use the internal memory or external memory using a memory card.

Types of cameras based on the mechanism

Single lens reflect camera

This camera has a flat mirror with 45 degrees uncover behind the lens, so that what is seen by the photographer in the window view is also what is going on catching the movie. These cameras are generally used by seriously photographer.

Pocket camera

The most popular type of public use. The main lens can not be replaced, usually automatic or require little light settings directly through the lens of the media to burn. The weakness of this film is the image captured by the eye will be different from that produced the film, because there are differences in points of view sight window (viewfinder)) with the lens.

TLR camera

Weaknesses camera pocket camera repaired by TLR. Given lens viewfinder that is identical to the lens underneath. However, there remains the parallax error is caused because the angle and position of the lens is not the same.
