Types of Cameras and Their Functions

1.     The types of cameras

a)   Types of cameras based on media catcher light
·         Movie camera

Type of camera film used was of type 35 millimeter, which became popular because of versatility and speed when shooting, since this camera is small, compact and unobtrusive. Sometimes interchangeable lenses, and cameras that can load a roll of film for 36 outcrops, sometimes even more.

·         Polaroid Camera

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

·         Digital Cameras

This type of camera is a camera that can work without using film. The photographer can easily capture an object without having to bother took aim through the window of view because most digital cameras do not have it. Instead, a digital camera using an LCD screen mounted behind the camera. The width of the LCD screen on any digital camera is different.

As a storage media, digital cameras use the internal memory or external memory using the memory card.


b)   Types of cameras based on the mechanism of action
·         Reflect single lens 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 of view is also what will be the catch on film. Generally these cameras use a waist-high when dipotretkan.

·         Instant Camera

The term instantaneous is its automatic mechanism in the camera, so that by measuring light (lightmeter or photometer), width of the diaphragm and shutter speed are automatically set.

c)    Distribution of the camera viewfinder based on technology
·         Pocket camera

The most popular type used in the general population. The main lens can not be replaced, usually automatic or require a little adjustment light passing through the lens directly burn medium. The weakness of this film is the image captured by the eye will be different from that produced the film, because there are different points of view sight window (view finder) with lens.

·          TLR Cameras

Weaknesses pocket camera repaired by TLR camera. The viewfinder lens is given identical to the lens underneath. But still no parallax error is caused because the angle and position of the two lenses are not the same.

·         Camera SLR (Single Lens Reflect)

On SLR cameras, light is deflected into the camera's eye so that photographers get shadow Photographers are identical to that will be formed. When the photographer pressed the shutter speed button, the light will be deflected back into the medium (or film). SLR camera lens can be replaced instead of according to the will, is favored to experts photograph, or a hobby, lens holder on the camera body differs depending on the brand of camera bodies, ranging from wide lens (wide angle), tele (long distance), and normal lens (standard 50 mm), is also a long zoom lens with lens varies

Analog Cameras

Is one category yangdalam camera shot techniques, are still using celluloid film. Celluloid film has three basic elements, namely an optical element in the form of various kinds of lenses, chemical element berupafilm celluloid itself, as well as mechanical elements which form the body of the camera itself. In addition, analog cameras require a diaphragm opening of 1 / f seconds, so the light is captured, can be accepted by the film into an image. In the life of the community, analog cameras are usually more familiar with the title film cameras. This is caused by the use of film in these cameras, a recording or storage media. The film is also commonly known as a cliche or negative.

EX: Analog Cameras 
SPECIFICATIONS ANALOG CAMERA
Description:- Film Advance: To move the film from first frame to the next frame.- Shutter Release / Shutter Release Button: The key to shooting- Film Speed Scale / Bracelet Shutter Speed: To set the slow shutter speed closed- View Vender: To view a picture- Penta Prism: To normalize the image upside down from a mirror which- Rewind Knob / lever winder: to roll fim who has been in use- SEFT Timer: To photograph the premises time- Mirror: To accept incoming images from the lens- Lens: To view the near and distant objects clearly whether or not an object

Digital Cameras

The digital camera is a type of camera, the image-making process is done digitally, with a media recorder / storage in the form of memory (flash). For some types of digital cameras, others can be used to record sound. In digital cameras, the use of chemical eleman has been replaced with the element chips. Elements of these chips can be a CMOS (Complementary Metal Oxide Semiconductor), or it can also be a CCD (Charge Couple Device). This CCD and CMOS, which will regulate sensitivity lighting. CCD and CEMOS also has become a "digital film", in modern cameras are currently available.
