Ev = log2 (n2/t) (or, since log2 (10) = ~3.322, ev = 3.322 log10 (n2/t) ) where. Each increment of 1 in exposure value. Maybe 1/30 at f16 with a tripod for alot of dof with a scenic with a foreground too. Some cameras can be adapted, as i did to my plaubel makina 67, which simplifies their use with spot meters.
