Question

Answer 1

Aperture is controlled by 'diaphragm' in optics.

Answer 2

Answer:

Aperture is controlled by the diaphragm in the camera

Explanation:

    The diaphragm in the photograph is the diameter of the lens aperture. This diameter is one of the factors that defines how much light will enter the camera, up to the sensor. The larger the aperture, the brighter the lens (better suited for low light locations).

• More open diaphragm = more light = smaller number.
• Closer diaphragm = less light = larger number.
