Aperture is known to be the lens diaphragm opening inside a photographic lens and is usually calibrated in f-numbers or f-stop. The Aperture of a camera is just like the pupil of an eye. It adjusts to the light by going smaller or larger. If there is a ton of light the aperture will decrease and let as much light in as needed and if there is only a small amount of light the aperture will increase by widening so more light is let in to be able to see the image clearly.

Learning about photography
ISO is the sensitivity to the light of a camera. On low sensitivity the film has to be exposed to light for a longer period of time then on high sensivity to properly expose the image. When you are outside you normally use low sensitivity because the light is bright enough and when you are inside you use high sensitivity and sometimes you need to use a flash to make the picture a little bit brighter. The ISO numbers range between 100, 200, 400, 800, 1600 and sometimes 3200.
Shutter speed is what controls the ability to demonstrate or stop motion, in a photograph. It is when light is exposed on your camera and the length of the exposure. The longer your shutter stays open the more motion it will have time to record. The shorter time your shutter speed is open, then there is more motion it can stop. Aperture and shutterspeed work together because the shutterspeed determines the amount of time your camera’s shutter remains open, and the aperture determines the amount of light that is let in within the amount of time determined by the shutter speed.
