Exposure is the science (and the art) of making sure the sensor gets exactly the right quantity of light to produce a good image. Exposure is adjusted using shutter speed (the length of the exposure), lens aperture (how much light is passed through) and ISO (the sensitivity setting of the camera). Camera’s have light meters to estimate the correct exposure setting but it’s sometimes necessary to override this with manual adjustments.
