I suggest Affinity Photo to support exporting High Dynamic Range HEIF (HDR PQ 10-bit) from RAW/DNG/ProRAW file.
It could really be a killer feature in photo editing across any OS platforms. It is especially beneficial to users who are using some recent MacBook Pros supporting HDR10/Dolby Vision (e.g. iPad Pro 2021 with XDR display). For web publishing compatibility, HDR-PQ AVIF could also be supported.
Please kindly support.
