Beauty AOV doesn't include Camera Exposure.
Could you elaborate?
We have all AOV nodes to control Camera Imager settings and Post except Camera Exposure :

"Adjust brightness" is the equivalent to the exposure setting in the imager node.

Unfortunately not. It doesn't work in 32bit space so it only simple darker highlights.

It's not possible to tell from your video, but you may be changing the brightness after an SDR node. Try placing the brightness adjustment before any other processing.

If you are still having issues, send me a simple scene.

It seems that the minimum value for the slider is 0.1 in the C4D plugin. Can you manually type in a value less than that? Other than that, it appears to be working correctly.

The problem was that I had Adjust Brightness after highlight correction thats flatten image to 8bit. The order is important.

Due to the float precision issue!?? Lol but no! Because the photon tracing "confirmed" the very good accuracy of caustics of 12M-spp rendered by path tracing kernel - check "5 cycles of number of spp from 1M to 12M (or 12 laps*(2) of 1M-spp)" - HERE.

Regards,
Can you check in device preferences whether you have only one of the two devices enabled for denoising? If that's the case, you should be able to work around this issue by enabling both devices for denoising until this issue is fixed.

It looks like AgfaColor Futura 100,200,400 and Futura II 400 Responses are exactly the same...

They are very similar, but not exactly the same. If you save two image files and compare, you can see that Futura 100 is slightly darker than 200 which is slightly darker than 400, and Futura II 400 is slightly darker than all of those.
