But monitors have dynamic contrast what should guaranteed quality color at all brightness. So even at low brightness monitor can show full spectrum color, color will be cut if i change brightness at video card driver. For sRGB mode for my model monitor was recommends 2 brightness with calibrator.

But i was telling what HDR content creators can't use HDR1000 for work, it's too bright and harm for eyes. And how this content may work at monitors with 8bit real colors i don't count fake 2bit FRS as it's just like dithering in photoshop?
Also 8bit video looks dull in HDR but i can change player settings so it will looks very similar to 10bit.
So i am thinking it some kind of ads than real advantages in colors, maybe for video it has more colors with compression, but in CG we are rendering every frame in full colors so they should have more colors than this fake HDR videos.

There is also the current issue of 10bit output being restricted to professional cards regardless of physical input in monitor. nVidia gonna nVidia. I wonder if HDR will force them to reconsider this stupid policy.

When you talk about colour though you actually mean chromaticity which doesnt take into account luminance aswell. By reducing the monitor brightness youre restricting the luminance values it can represent and therefore restricting the colours available on your shiny new HDR monitor.

This has changed. As you mentioned HDR forces them to output at higher bit depth.
But they are not stupid XD it seems that you only get 10 bit when playing games. So basically it only works when launching Direct X.

So Yes, you still need Quadro

You're right ! I think this how the policy exception worked for longer time. I think it's both DirectX and Fullscreen at same time, or something like that, for GTX.

Might be personal preference. I prefer Tiff for the following:

- more commonly accepted in all of its versions (16bit&32bit Tiff, whereas 16bit PNG (PNG-48) is less).
- more compression options
- more flexible alpha use (lot of applications read png with baked alpha, with Tiff they always give interpretation options)
- can save layers, good support for color profiles

It's good format to save from Corona, good format to store layers, good format to send to clients,/print.

So are you saying that you save your still images out of the Corona VFB as "16-bit Color" TIF images...? Assuming No Compression and 300dpi - to complete the TIF image control dialog?

In your opinion, would this be the best "photography" type work flow... ie. DNG -> Lightroom -> PS...?

Sorry if this is rudimentary, but a lot of this thread is well over my head...

Just saw this thread got bumped again so wondering if Dubcat or anyone else has got any more LUT/VFB wizardry for us?
Vray who?

I too am interested in seeing what else everyone is up to on this topic. I had a bit of fun with the 3DLUT creator using the photo match tool - makes matching reference photography easy and then you can load this into your VFB for further adjustments (or just keep it as an adjustment layer in photoshop).

This is awesome. Do you have access to FStorm by any chance? Would be great to see how close we could get to emulating it's fantastic standard tone mapping vs some good baseline Corona VFB settings. I've attached Dubcat's 99% accurate ACES VFB settings that he posted a while back.

I believe in dubcats hideout thread theres some fstorm LUTs
