Aperture


Aperture controls the amount of light that passes through the lens and the consequent impact on the camera sensor. It affects the brightness of the resulting image. It is a device that changes the size of the opening through which light passes.
  • The smaller the aperture, a greater amount of light enters the camera and the brighter the resulting image.
  • The smaller the aperture, a shorter shutter speed is needed to achieve a brighter image.

Effect of aperture on depth of field

Setting the aperture together with the lens focal length, the shooting distance and other factors affecting the depth of field. Depth of field is directly proportional to the aperture value.

  • Smaller apertures transmit more light and less depth of field, achieving result such as portraits with a sharp face and blurred background.
  • Larger apertures are less permeable to light and depth of field, achieving result such as landscape photographs with sharp foregrounds and backgrounds.

F-stop number

The aperture value and luminosity is determined by the aperture value (F). Aperture and light transmission apply in an inverse relationship.

When you set a small aperture of F1.8, compared to an aperture of F11:

  • The hole through which light passes is greater.
  • It has greater luminosity.
  • The depth of field is smaller.
