The Exposure triangle is based on three methods of controlling your cameras image – ISO, SHUTTER SPEED, APERTURE which combined create a perfectly exposed picture.

  • ISO – the measure of a digital camera sensor’s SENSITIVITY to the light.
  • Aperture – the size of the opening inside the lens when a picture is taken, essentially how much light is lets in. This is the QUANTITY of light that is hitting the sensor.
