Color correction - saving EXR and color depth

Hi…
I am litle bit confused.
I would like to render my animation to 16bit float depth, but width Reinhard color correction in vray. I am using in my scene Reinhard with burn value 0.2, which is doing nice soften light. I am also using gamma 2.2 in gamma setting of color correction and max setting.
The problem is, when I render image and save as vrimg - exr, the exr is just 8bit per channel. It is written in 16bit float, but information is just 8 bit per channel. I don’t understand why. When I tick option: Don’t affect color correction (adaptation only) then to my render isn’t played any color correction ( I need them) but exr is really 16 bit float.

I am just struggling…I am not having problems with lwf, gamma, exr and depth…also compositing channels together. Works perfect. But only if I am working without any color correction in vray.
But now, I am rendering interior scene. I was working on that with reinhard color correction and burn value 0.2. This is doing nice soft light. But I would like to switch the project to Fusion and when I tick on: Don’t affect colors, and trying do the same color correction in fusion I am just lost…I can’t get so nice soften light like with vray reinhard. I have tried to applied gamma, gain, contrast, brightnes…but still in soften areas it is burned so much… I don’t know what is the best workflow.
Is there any way to put color correction in vray and still don’t lose any facts for compositing?
I am really lost…I don’t know the way…

Not currently possible. As others have said however, in post you can apply “color mapping” like reinhard by adjusting your curves. In off topic I think it was, some1 posted what the curves should look like in Nuke. I take it that it should also work for Fusion, AE etc.

hmmm, and is it normal that when I ticked off the option: Don’t affect colors (adaptation only) The exr had just real 8 bit per channel?, but Fusion was saying 16bit float? I mean, the real information was just 8 bit per channel but in format information was written 16 bit float. That point is very confusing for me. I though, when I do anything, except Clamp colors, output is every time more then 8 bit. But at this case, isn’t.

I’m a bit confused by what you mean about real 8bit and written 16bit, do you mean that you clamped the output and saved a half float output?
anyway, gamma settings, or colour correction in general, is not related to the image depth of the format in which you decide to save your files. ticking “don’t affect colours” should not affect the actual depth of your EXRs.
