JPEG XL support has officially been removed from Chromium

DSLR market has pretty much stopped (rarely any new DSLR camera is released) as everyone shifted to mirrorless cameras. Camera manufacturers mostly added HEIF (Canon, Sony, Fuji) as the non-RAW image format, because they already have HEVC for video.

Camera with a lossy / lossless 12-bit, 14-bit JPEG XL would definitely be interesting for many photographers. Not everyone wants to be forced to do a complete post-processing with RAW. JPEG is to limited (8-bit only) and HEIF isn't much better, while not having much support (especially on the web) because of the patent situation.

Fully agree with this sentiment.

Also good to know that Jpegli (a traditional jpeg codec within libjxl) allows for 16 bit input and output for '8-bit jpegs' and can deliver about ~12 bits of dynamics for the slowest gradients and ~10.5 bits for the usual photographs.

Jpegli improves existing jpeg images by about 8 % by doing decoding more precisely.

Jpegli allows for encoding jpeg images 30 % more efficiently by using JPEG XL adaptive quantization (by borrowing guetzli's variable dead zone trick), and the XYB colorspace from JPEG XL.

Together, you get about 35 % savings by using jpegli from the decoding + encoding improvements. Also, you get traditional JPEG that works with HDR.

Jpegli is predicted to be production ready in April or so, but can be benchmarked already.
