What is a DSLR camera?

Once you are through with the use of mobile phone camera & digital camera, it’s time to move up the ladder.  The next step is to own a DSLR Camera but before that, you should know what actually a DSLR Camera is. Using a DSLR without understanding it is similar to driving a car without any training. 

DSLR Camera
A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. Earlier in a photographic SLR Camera instead of digital imaging sensor a Photography film was used on which image was captured and after processing it could be printed on paper.

Working of DSLR Camera.

How DSLR Camera Work
We all know light travels in straight direction and it is main element for photography. Without the source of light, photography cannot be done. The main parts of a DSLR Camera are
  • Lens
  • Reflex Mirror
  • Matte Focusing Screen
  • Pentaprism
  • Eyepiece
  • Focal-Place Shutter
  • Sensor

Each of these parts performs key role in photography such as
  • Lens helps in focusing, zooming in out and has the part which control the aperture. The light is passed through the lens, which is then reflected by the reflex mirror.
  • The Reflex Mirror helps in correcting the inverse image passed through the lens. The image is then projected through the Pentaprism and could be seen in the area of eye piece by the person. This entire process is in real time without any delay.
  • Behind the Reflex Mirror, the Focal-Place Shutter mechanism is located, which controls the speed of the shutter. The speed of the shutter is similar to the lid of the eye, the higher the shutter speed; the lesser is the time duration for the exposure of the light and vice versa.
  • Whenever a click button is clicked the reflex mirror goes down with controlled shutter speed and image is imposed on the sensor, which captures it in digital format.
