Exposure and tone mapping in Corona's vfb

Corona Corona for 3ds Max General

I’m not posting this in bug section, just because i’m not sure if it’s a bug or that’s how it’s intended to work, but all that exposure and tone mapping thing in corona, bugging me quite a while. I did a bunch of tests this evening and things became a little clearer, but there is still few things, that i’d like to know.

  1. photographic exposure mode is not adjustable when rendering, is this thing possible to fix?
  2. in arbitrary EV mode, original RGB values via right click in vfb, are reported incorrectly, i think. Will it be fixed?
  3. wouldn’t it be good idea to replace arbitrary EV in UI with common EV values? Exposure value - Wikipedia

First of all, thanks for answers, Rawalanche.

I would like to clarify more on nr.2 if you don’t mind. If you say, that it behaves correctly in arbitrary EV mode, then doesn’t that means that behaviour in photographic mode is incorrect? Because reported original RGB values are changing with exposure.
