How a digital camera works?

The art of photography is seeing and balancing the light. This is done by camera using lens, aperture, shutter and censor.



1. The light reflecting from an object first goes through the lens. 

2. The aperture unit placed inside the lens help us control how much light reaches the sensor.

3. Shutter placed inside the camera has a mechanism to open and close a window for light to travel to sensor. It controls how long the sensor is exposed to the light
4. The sensor is a very sensitive electronc plate which absorbs light and transform to a pixel with colors.
