Title: Exposure (EV) not working
Post by: BBB3viz on 2014-07-01, 08:43:25

In A7, in the ColorMap section of the tools, Exposure (EV) seems to have no affect at all on the image, whereas Highlight Compress, Contrast and WB all work as expected.

Are you sure you have not enabled "Use photographic exposure" checkbox? (Found in exposure and color mapping rollout of render settings) In that case, EV is ignored, and exposure is derived from the combination of ISO, F-stop and Shutter speed parameters, so it behaves like real camera. Once you enable Use photographic exposure, EV parameter in render settings freezes to imply that it is no longer used. Unfortunately, Keymaster forgot to freeze it also in Framebuffer panel :)

That's possible. Let me check when I can access the scene again.
