T-stop to f-stop calculator
WebThe t-stop is calculated by dividing the f-stop by the square root of light transmittance such that a lens with an aperture of 2.8 that features a 90% light transmittance will have a t … WebThe f-stop explained. F-stop is the term used to denote aperture measurements on your camera. The aperture controls the amount of light that enters the camera lens, and it’s measured in f-stops. Along with shutter speed and ISO (sensitivity to light), aperture is the third fundamental component that makes up the exposure triangle in photography.
