Aperture

Also known as f-stop, f-number. Category: Lighting and optics

The aperture is the adjustable opening in a lens that controls how much light passes through, expressed as an f-number (f/4, f/8, f/16). A higher f-number means a smaller opening, less light and a greater depth of field.

How PhotoRobot uses it

PhotoRobot notes that greater depth of field requires a higher f-number, which in turn demands more light intensity; this is one reason it recommends strobes for larger products. PhotoRobot Controls sets aperture remotely on supported Canon cameras.

  • Depth of field: The distance range in front of and behind the focus point that appears acceptably sharp.
  • Exposure: The amount of light that reaches the sensor, set by aperture, shutter speed, ISO and light output.
  • Hyperfocal distance: The focus distance that gives the maximum depth of field, extending sharpness to infinity.
  • Focal length: The lens property, in millimetres, that sets the angle of view and magnification.
