The fundamental function of a digital camera and the film camera is almost the same. Both the cameras use lenses, shutters and apertures. The lens of a camera captures the brightness or the light that is passed into the aperture. This aperture controls the light and the shutter then opens and closes accordingly in order to control the time of light that enters. One of the main differences is the technology of detaining images. Normally a digital camera does not use a film to capture and store images, instead in the digital camera an image sensor is been utilized to capture images which is a computer silicon chip. On the exterior portion of the chip are millions of pixels that are known as photosensitive diodes.

The shutter button in a digital camera normally works as a metering cell that manages the aperture and speed of the shutter according to the amount of light that comes via the lens. When an individual clicks on the camera shutter all the pixels of the image sensor stores the power of the light that falls on it by assembling an electrical charge. When strong light hits these pixels it creates high charge and when weak light hits it creates low charge. As the shutter closes the charges from all the pixels are converted into digital numbers and these numbers create a digital image on the normal computer screen.
