I've been trying to use Photoshop to post-process my EXR renders just like I'd do with DNG files. You know better than me the difficulties of this, since Adobe Camera Raw does not support 32 EXR files. My current workaround is to check the "Use adobe Camera Raw to convert documents from 32 bit to 16/8 bit" option in Photoshop preferences. This way, every time I load a 32 bit EXR render in Photoshop and change from 32 bit to 8 bit, Photoshop will launch ACR in order to tonemap the image.
However, after messing around with this method for a while, I've started to question myself wheatear this is really working or not since it doesn't really feel like editing a real RAW image. I mean, am I really being able to access the whole dynamic range of the EXR using this workaround? If you have already tried this method, I'd love to hear your thoughts about it.
