► EDIT : There is "now" ACES working with OCIO http://opencolorio.org/configurations/aces_1.0.3.html

Well in case you missed it...

Thanks. I would like to point that OCIO is not an artistic LUT like the trend of nowadays in fstorm and corona. OCIO is more a professional "tool" and actually you should read the links I posted.

Also : All my outputs are RAW with no pre-post from the frame buffer. This is another way to pre-vis final look and actually really handy for look-dev in VFX. 

Applying a LUT for quick color grading is...not color grading. It's handy for people who dosen't know about color grading /previewing a look but "not how it should be done".

@NEO-N
do you know if 4d cinema with Corona has a dynamic range limit? I was reading the Blender post where it has a limit of 8 stops

openEXR will give you a very high dynamic range, more than what you can see/need.

Blender filmic is linear + instead of sRGB you've got filmic to replace it from what I understand and as far as I remember (i don't use blender). No matter what renderer you use, they all output linear openEXR which can gives you the best results for any situations (movie, printing, internet, etc). All you need is to finish in post with a software to get it to whatever you want (sRGB, rec709, DCI, etc) : Photoshop (not a complete color management app but it works) - Affinity as well then pro softwares : Nuke/Fusion/Davinci Resolve (I used blackmagic softwares with ACES and OCIO workflow color management).

thank you so much!
I'm learning Fusion, but I'm also evaluating Affinity Photo which works in 32 bit.
Many times I evaluate the idea of doing the dof in post production with these programs. in any case I always go out with Exr format: D

DoF in post is even used in high-budget movies. Faster render times, more flexibility. Not all renders have a very photo realistic camera shader (to mimic real life lenses). They capture real life parameters of a lens, and try to mathematically/digitally re create all of it.

You don't know what I'm talking about ? Check this out : http://zenopelgrims.com/zoic/

C++ programmed camera shader for Arnold (not working with Arnold 5 yet). They basically do the same but in post.
