T NUMBER
A measure of lens aperture commonly used by cinematogra-
phers. Lens transmittance is taken into account to better cal-
culate exposure.
F NUMBER
A measure of lens aperture commonly used by photographers.
Lens transmittance is assumed to be 100%, meaning that the
same aperture may produce diff erent exposures depending on
the lens.
