The term 'Camera Part' refers to the four main components of a camera: an IRIS, a LENS, a SHUTTER, and an APERTURE. The IRIS is a diaphragm that controls the amount of light entering the camera. The LENS is a curved piece of glass that focuses the light onto the film or digital sensor. The SHUTTER is a mechanism that opens and closes to control the amount of time the light is exposed to the film or sensor. The APERTURE is a hole in the LENS that controls the amount of light that passes through it. All four of these components work together to create the image captured by the camera.
