In: 0
Modern digital cameras have image sensors. These sensors have thousand and thousans of cells that change their charge based on what color and intensity of light touches the cell. The camera reads the charge of the cell and interprets it to a pixel on a screen or photo.
Simply put: light passes through lens to be focused, light hits something that can detect it.
Film Cameras: The light hits some chemicals that are sensitive to light on a sheet of plastic, the chemicals change when they get hit by light and record an image of the light.
Digital Cameras: There’s a grid electronic sensors that that can get some electric charge when a bit of light hits them, they’re like a bucket and it fills up with charge until it’s completely full and then you have a white pixel.
