@alexfry thanks for sharing this updated workflow for Photoshop.
I was testing your process in Blender > Photoshop workflow. I used ACES in Blender and images looked as expected with your LUT in Photoshop.
Can I make a request? While I understand the benefits of ACES, right now Blender doesn’t offer the best experience when you force to use it. At the moment Filmic is just more convenient. Would it be possible for you to produce a LUT that works with Filmic based workflow?
I tried to do it myself but the color science gets too complex for me here and I couldn’t make a correct LUT.
Although, I used your LUT and it worked surprisingly well with Blender output of 32bit EXR image. The only thing I had to adjust was to make a tone curve lifting shadows and mid tones to match Filmic look. I understand it’s not very accurate, that’s why I’m asking if you can produce a proper LUT for this workflow.
It would be very helpful while we’re waiting for Blender to implement full support of OCIO and ACES standards. Which should happen relatively soon as I gathered form latest updates.
If not, it’s totally ok. Maybe I’ll eventually be able to figure it out on my own. 
Thanks.
