On a number of occasions I have seen references to exposure value (EV) worded such that a larger EV implies "more" exposure. I recently read (in a forum here) "...low light needs more exposure values".
Now this appears to be back to front to my understanding of EV, and maybe I have been misunderstanding what some have meant when they refer to EV, or maybe there are different definitions.
Wikipedia (http://en.wikipedia.org/wiki/Exposure_value) gives a good definition of EV, which accords with my understanding, and provides a table of exposure times for various exposure-values and f-numbers.
Here's a couple of examples...
f-2.8 at 1/1000 sec = EV 13
f-2.8 at 1/500 sec = EV 12
f-2.8 at 1/2000 sec = EV 14
which implies that higher EV means less exposure, lower EV means more exposure.
So, as they would say in school..."please discuss".
