> Being P3 (WCG) doesn't mean it's also HDR or that it's calibrated well or that the display software is handling it.
There are plenty of monitors with both a larger gammut and higher dynamic range.
> So you can combine them how into what? There's no good software for it. HDR combining software typically creates SDR images, not eg EXR files, and it usually looks bad doing it.
So you can combine it into a raw image with higher dynamic range. FF cameras generally have 12-13 stops of dynamic range without bracketing at 14 bits per channel, so you can absolutely tonemap them into an HDR image, even without bracketing. With bracketing, you can generate a raw image which will have 24 bits or more of dynamic range, which will actually be useful.
I'm not talking about cheesy HDR combining software, I'm talking about, for example, combining images into Lightroom with a high bit-depth workflow which can then be exported as an EXR or TIFF image. There's plenty of software that can generate even higher bitdepth, and these are often used in CGI to generate HDRI maps, for example.
The dynamic range of the actual image of the camera far exceeds any screen you might show it on. You're really only limited by the noise floor (which is close to the theoretical limit).
> What's that got to do with HDR?? Surely reflective media has less dynamic range than transmissive media…
Reflective media has theoretically infinite dynamic range, you're only limited by how black your black is and of course by the printer.
