    DSLR means "Digital Single Lens Reflex". DSLR camera is the mostly using camera for photography. Here we'll try to take a basic scientific approach to understanding how a DSLR camera works bellow the article. 

How It Works

    When you looking through view finder, whatever you see which means that you could be looking at exactly what you are going to capture. The moment you hold up the camera and start focusing, the camera begins to read the light that is coming through the lens. The Reflex mirror sits at a 45' degree angle inside the camera. Then forwards the light vertically to Pentaprism. The pentaprism convert the vertical light to horizontal by redirecting the light through to mirrors. Then you can see what you are capturing from View finder. 
                                                   When you taking a picture the Reflex mirror swings upwards and blocking vertical pathway to letting the light directly through the Shutter opens up and light reach the Image sensor to record the image. Then shutter closes and the reflex mirror drops down. This processing doesn't stop there.  Lot of complicated processing happens on the camera. The camera processor takes information from the image sensor converts it to digital image. Then writes it in to a memory card.  This is a very simple way to explain how DSLR camera works.
