The existing HEIF 10 export is very useful but I have been standardising on jpeg xl for my film scans. Please could jpeg xl (16 bit included) be added to the list of future features Nik? I believe Rawtherapee has this so there are likely to be open source libraries available.
It’s on the list to do, but that is predicated on Apple having support for JPEG XL export in their libraries. I do not use open source libraries for this because that would require a completely separate code path.
