The basic operation of the digital camera and film cameras are the same thing. Both use the shutter speed and aperture. Objective catch the light, and then passes the diaphragm, which controls the light and the shutter opens and closes to control the length of the light that enters.
The big difference is that technology has taken the photo. Digital cameras do not film the image to save it. In a digital cameraimage sensor is used to take the picture. This is a silicon chip. On the surface of this chip there are millions of pixels that are sensitive diodes.
Digital camera shutter button once again, a measuring cell where the shutter speed and aperture based on the amount of light through the control lens. When a user clicks the shutter of the camera each pixel in the image sensor affect the intensity of light falling onTo this end, assembling an electrical charge. When strong light strikes a pixel, resulting in high costs and low lighting create a low price.
When the shutter covers the cost of each pixel is converted into digital numbers. This series of numbers, creating an image on a computer screen.
