Sexy! Now hide the gamma spinner. ;)

That looks nice indeed.

Sexy! Now hide the gamma spinner. ;)

With all due respect I wish this conversation was over by now. You are confusing imitating photography (therefore not playing with gamma) with creating images, the latter of which sounds more appealing and what you are implying is tools should be restricted because your taste differs from mine. Choose not to play with gamma and be happy, don't try to make the decision for the rest of us.

Finally!

vkiuru : well said :)

I still can not believe people are so close-minded. Gamma is NOT a means of artistic control. It is not like it is another tool that can be used. It is something that should be hard coded in most of the modern applications. With gamma you do not change just what the output is, you chose to display very different color range where for example sampler does not resolve noise. You can end up with a lot more noisy renders, or with totally wrong normal/opacity maps if you open them with wrong gamma. Or having post processed motion blur/DoF not working correctly. Gamma changes a lot more than just perceived colors.

For example, in Vray, if you have wrong LWF set up, you might end up with significantly longer rendertimes as adaptive sampler resolves noise at levels very different to those you perceive through wrong gamma. Use whatever works rule does not apply to gamma, especially now, when correctly working contrast function is implemented.

If you, even after this, decide to play with gamma, then fine. Just please do not mention it here as if it was just another feasible workflow, because it can confuse a lot of new users.

Sorry, didn't mean to start a flame war. ;)

Could there be a separate implementation of gamma correction that only works as a post processing effect? Or maybe it would do the same as the new contrast function? Such feature might calm down some people. :)

Incredible.. Why is it so hard if you so must change gamma values, to do so in post??? In corona you have so much easier not to manualy setup LWF and you still wanna do it the hard way :D LOL

infirst - gamma changing affects not like contrast changing or postproduction changing - you can set lights and mat like you need before press render button

in second - why so many talk about gamma? Why is bad that gamma would be simple hiden like now in debag settings or in another hiden tabs?

Gamma wars :- D It's always russians/chinese (no offence, just observation) who intentionally "break" software in funny ways to achieve something that could have been achieved in much more logical way. I wonder who ever started to use gamma as way of contrast....

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.

[Ondra]

yeah, yeah, just wait, in time I will satisfy even people with pathological fear of photoshop loading screen :D

[Juraj]

Heh,c'mon, this stuff is the only useful thing about Vray frame-buffer :- ). Let's you visuale more closely what your end result will be.

[Ondra]

or maybe photoshop could be loaded in the VFB as a plugin :D

I would pay big money for that
