Aperture controls the size of the opening through which light enters the camera. Shutter speed together with aperture determine the amount of light reaching the sensor or film, with exposure value accounting for both shutter speed and aperture. ISO is similar to film speed and controls the camera's sensitivity to light, with lower ISO numbers meaning less sensitivity and requiring more light than higher ISO numbers.

- 2. Aperture • An aperture is a hole or an opening through which light travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane.
- 3. Shutter Speed • The camera's shutter speed, the lens's brightness together determine the amount of light that reaches the film or sensor. Exposure value is a single quantity that accounts for the shutter speed and the f-number.
- 4. ISO • ISO is similar to film speed on film cameras. Unlike aperture and shutter speed, ISO doesn't control how much light enters the camera, but instead controls how sensitive the camera is to that light. The lower the ISO, the less sensitive the camera is. In other words, a lower ISO will require more light to properly expose a picture than a higher ISO.
