| aperture |
The opening in the lens that controls how much light hits the camera`s image sensor. The aperture is an iris in the lens that can be opened or closed to allow more or less light into the camera. The smaller the aperture the less light it allows to enter through the lens. This is one of the ways a camera regulates exposure

| aperture |
In any type of camera, light is focused by the lens, through an aperture and onto the focal plane. The size of the aperture controls how much light passes through to the focal plane. In addition to controlling the brightness of the exposure, the aperture controls the depth of field in the image. By balancing the size of the aperture (as measured in f-stops) with the shutter speed you can trade off between varying depth of field, and or the ability to better-resolve fast motion.
