Anyway, the contrast tool is ok, but what would eventually be really cool, would be full curve editor. Most of the time I like boosting midtones, not highlights or shadows.
Strongly agree with Juraj, curves would be a must for me.
PS. Hello everyone, first post here :) Just downloaded Corona yesterday and really enjoying playing with it so far!
Hi and welcome!
Contrast function is there so that people do not touch gamma. Some were using gamma to make their renders more contrasty, which was wrong. So far, it is not intended for corona to be a post processing package. I agree that curves are great for quick preview, but they will need to be implemented carefully so that it does not bloat user interface or is not painful to use (like in case of vray).
At the moment, primary workflow is simply to post process the output in external packages, like photoshop ;)
