Hey,
When I render my final image in multilayer EXR and open it it After effects or Fusion, and work with a proper workflow to convert it to sRGB it shows me an overexposed image. I didn’t have this when I render with Arnold for example.
When I render the same scene and save it as a png, I don’t have this issue. Any settings in Blender for exr I should change?
Did you change the exposure in the blender color management settings?
Zombie revival - did you find out why? I read somewhere else (Otoy) it has something to do with Multipass and Linear instead RGB color space. So I tested a bit, but I don’t really know what I’m talking about…
How does this:
become THIS after Denoising?
There’s absolutely nothing remaining of the little interior present inside the apartment. In fact, it looks like what ppl associate with meeting their maker 
I tried setting the Filmic contrast to “none” (previously “very high”), that was much better, but still unrealistically high. Especially the brightness inside the apartment completely throws me off, this is simply JUNK.
Low contrast (much better):
Very low contrast:
Since I’m rendering animation files, I can’t process them in Photoshop as I usually did to avoid learning to use the compositor 
But I guess there’s no way around that, right? In AE, I can only shift the white point, which will darken the entire image, just like Film exposure in Blender. There’s supposed to be an “HDR” setting somewhere, which I can’t locate (using E-Cycles).
Using Curves now in the render settings, that should render OK for AE import?
highlights taken back:
highlight taken back more, slight contrast in curve mid & low end - STILL blowout:
Suoer, super lost! This is not Photography 
Do you have a version of this render that is high-samples instead of relying on denoising? My first guess looking at these is that the bright denoised version is actually correct, the noisy one just looks darker because too few of the bright light sources have been properly sampled. The denoiser (correctly?) guesses that more light samples will be as bright as the few hot spots it found and the correct lighting result is to interpolate that brightness everywhere.
EXRs hold far more data than a general JPEG or PNG. Because of this they will appear “overexposed” when converted to an ordinary image, even though the “overexposed” areas still have all the detail. You have to change the contrast values (in whatever your editing program is) for the EXR to not look overexposed. Just make sure you change the contrast values before converting to 8-bit.
