Exposure triangle

Meaning in photography, with examples

nounCore term

In photography, exposure triangle means: A simple model showing how aperture, shutter speed and ISO work together to control exposure; changing one usually means adjusting another.

In Turkish: pozlama üçgeni

How it is used

A teaching term heard in beginner courses, books and tutorials rather than on professional sets. Teachers use it to explain trade-offs: a faster shutter speed needs a wider aperture or a higher ISO to keep the same exposure.

Example sentences

  1. In the first lesson we'll cover the exposure triangle and practice in manual mode.

  2. Once the exposure triangle clicked for me, I stopped relying on auto mode.

Common collocations

  • understand the exposure triangle
  • balance the exposure triangle
  • the three sides of the exposure triangle
  • exposureThe amount of light that reaches the camera's sensor or film when you take a picture; it decides how bright or dark the final image looks.
  • apertureThe adjustable opening inside a lens that lets light through. A wider opening lets in more light and gives a shallower depth of field.
  • shutter speedThe length of time the shutter stays open to let light reach the sensor, such as 1/1000 of a second or two seconds.
  • ISOThe setting that controls how strongly the camera amplifies the signal from its sensor. A higher ISO makes the image brighter in low light but adds noise.
  • manual modeA camera mode, marked M on the dial, in which you set the aperture, shutter speed and usually the ISO yourself, and the camera changes nothing.
