DSLR: Digital single-lens reflex
DSLR is a digital camera that stands for digital single-lens reflex and comes with other compatible lenses that can be switched as and when to the user’s choice. DSLR is a unique blend of optics and mechanism of single-lens reflex with the modern digital imaging sensor. A digital camera wherein a mirror directs the light from the lens to viewfinder. The viewfinder is situated on the back of the camera that is typically a hole allowing to get a sneak peek of the image to preview it before capturing it.
Parts of a DSLR Camera:
These are the major units that constitute a DSLR camera:

Functioning of DSLR?
- Light upon entering the camera lens hits the reflex mirror.
- The reflex mirror resonates/reflects the light vertically upward onto the focusing screen.
- Through the focusing screen, the light gets in the pentaprism (a block of glass).
- Pentaprism deflects the light over two separate mirrors diverging it towards the viewfinder
- Viewfinder provides with the live and natural preview of the image.
- The reflex mirror is flipped upward, blocking the vertical path of light to maintain the straight path onto the image sensor when the button is pressed to capture the picture.
- When you click the button to take a photo the reflex mirror flips upward and blocks the vertical path of light to keep it straight towards the image sensor.
- Light reaches the image sensor when the shutter opens up.
