Exposure Value /EV/ system expanded to include filter factors and transmittance
Abstract
Application of the exposure value system requires that the system be extended to high brightness level and expanded to include filter factors. A minimum of four photographic factors are involved in the evaluation of an exposure which, when determined from tables of 1-stop interval, could introduce noticeable error.
