Commands used on machine running Debian free software after saving both 16 bit TIFF and JPEG from Canon DPP software (jpegli was built from the libjxl source code on this machine) :

I was influenced by https://www.nature.com/articles/s41467-025-64679-2 to use 4:4:4 quantization instead of the 4:2:2 quantization done by DPP. "Ashraf, M., Chapiro, A. & Mantiuk, R.K.
