To not start a new topic 'cause it's along the same lines: Canon R5's HDR PQ RAW file support. Please. The R5 applies a PQ curve when HDR is activated to RAWs (better highlight rolloff) and Affinity Photo reads the data fine but has trouble interpreting the color space correctly. Please add support for these RAWs. P.S: If some test files are needed please contact me, I'm happy to help.

Update: The problem is almost solved: In the development persona, the assistant is set to develop to 32bit and then the process aborted (the settings are saved regardless) and then the RAW files are batch processed to 32bit TIFF, then stitched. Now it works, right up to the stage where the pano is rendered. Before the info in the highlights is there (and visible in the preview) but afterwards it gets pushed into oblivion and the result is the same as in the beginning when done in 16bit, even though the panorama is correctly opened in 32bit HDR.

Here's the example. One is the RAW file developed with -100% in the highlights. The other is exported as 32bit tiff, then the highlights brought down 100%.

RGB/32. But EXR should also work theoretically, as you cannot overexpose an EXR. I use the batch-processor to "develop" the files, I don't do it manually.

Let me add to that: I'd be happy if I could load RAW files to merge into a panorama, that are loaded with 32bit color depth. I've tried merging RAW photos of my R5 into a panorama but the clouds next to the sun get clipped. I've exposed the RAW files accordingly such that there is no clipping whatsoever and I can bring back the detail when opening the file separately but no matter how I combine them (directly, via EXR, via TIFF) highlight detail is irreversibly lost. So: I'd like a method of combining the RAW photos into a panorama, without loss of information that I can develop afterwards, such that I don't need to develop a myriad of photos to then combine them.
