2025-07-31 09:19:49	Actually, JXL should be able to handle linear transfer extremely well, if tagged so.
2025-07-31 09:22:00	what's the input format, PNG? if untagged, JXL will assume sRGB

Lilli

2025-08-05 09:31:24	I see, the input is accumulated raw camera data, so it's float32
2025-08-05 09:31:44	And sometimes I have some uint16 too

Can JXL handle raw as input? If it internally assumes sRGB transfer for RAW, that would be possible, although really not how it should be...

you can ask for linear sRGB in the options, so that kinda works fine, it performs as expected for me
