The camera is the image recording device. Meaning of the camera is actually a room, that is to say: a dark room, taken from the Italian "camera obscura" which means a dark room (dark chamber). And indeed the room was very dark inside the camera. The creation of a very long history of cameras and involve a lot of pioneering inventions and inventors.
Camera parts

The main components of the camera are:
  1. Photographic lens
  2. Lens holder
  3. diaphragm
  4. Focal plane shutters
  5. Photographic films
  6. Strap hole
  7. shutter release
  8. Film Speed ​​Scale
  9. Expose counter
  10. viewfinder
  11. flash socket
  12. Focus ring

How it works:
When the button is pressed, the diaphragm will open instantly. Light reflected from objects in front of the camera in through the slit diaphragm and penetrate up to slab very light sensitive film.
Diaphragm closes automatically and abruptly. Light entering the slab burn movies. Bright light will make the film layer burning (burning) are basically dark light does not burn layer. The next process "WASH" sheet film for combustion. The results of this process are: corny / negative. In the process of this "residual charcoal burning" so the film being wasted white / transparent. Being black remained unburned.
Next is to transfer the film (negative) to the photo paper (positive) or "PRINT". Term this process all kinds: calotype / Ambrotyp / tintype / Ferrotyping etc.. This process must be done in a dark room, because the light will affect the trasfer process. Paper used is a special photo paper that is coated ferrous compounds.
Different black and white photos and color photos are located on the movie. Films for black and white photographs only one layer comprising silver halide salts. Color film being composed of at least 3 layers. Where each layer consists of a mixture (chemical composition) of different.
