Since camera first time be created in the year 1826, its development become very fast from year to year.Technology that be used continue be developed with a purpose yield camera with result more good and simple. Its top with invention digital camera with technological breakthrough from use the film to digital system.

Digital camera and manual that marginally and its activity principle is same, its difference besides use of screen of LCD that present estimate of object result that will be taken its picture, digital camera also negate film like at manual camera and be changed with component so called CCD ( Charge Couple Device ). So that if at manual camera, light that enter will touching the film while at digital camera light will touching CCD to be recorded its picture.

CCD ( Charge Coupled Device ) is a sensitivesemiconductor to light which structured from millions of small spot so-called pixel. When light be accepted by CCD each pixel turn into electrical wave that generate colour according to light wavelength. There is also certain digital camera that not use this CCD but wearing CMOS have work function equal to CCD.

The excess of digital Camera :
  1. Not wearing of the film.
  2. Result of photography can be corrected direct.
  3. Directly can be connected with computer.
  4. Quality of picture will not be downhill if kept.
  5. Easily to be kept and printed.
