The only reliable raw converter that can handle Fuji color is Capture One. But they have collaboration with Fuji, I don't believe that conversion algorithm is open sourced.

But it would be interesting if AI coding agent could potentially reverse engineer the algorithm.

I always recommend RawTherapee for serious photography work. In addition to having been (at least originally) written by a complete colour theory geek and featuring a treasure trove of knowledge in the form of its companion RawPedia, it supports a whole host of raw formats, X-Trans RAFs among them (although Foveon X3Fs regrettably still an open issue).

I appreciate RawTherapee too and used it for a long time, but I started to notice that it really can’t match DPP for rendering Canon raw images. The denoising is nowhere near as good and it takes a lot of work to make the colors come out as good as DPP which has same processing profiles like “Faithful” that just look great out of the box.

What is DPP? I find it courteous in a conversation when the full name is provided before the first occurence of an acronym.

I had to look for it and for those who are as puzzled as I found Canon Digital Photo professional (RAW Image Processing, Viewing and Editing Software).

Pentax user here (hobby level), I am not aware of the other brands ecosystems.

Denoising is a weak part of RT, but I find with proper lighting it is rarely needed… At least for my use cases.

I have one Foveon camera, any hope for Foveon X3Fs support outside of RawTherapee? DarkTable does not process them correctly either

Like the native Fujifilm software, this does not do raw conversion itself. It uses the processor in the camera to do the conversion.

Smart move of Fujifilm. That will the future of software licencing with AI breaking copyright. Software will come encrypted and only run on secure processors. AI will push us further into an age of cloud, software DRM and software patents. The rest will be effectively public domain.

AIs will reverse engineer the processing algorithms based on observing a few example inputs and outputs...

Actually I give it a try … the results is interesting

I will share it shortly

Doesn't Adobe Lightroom these days also have proper RAW conversion and the Fuji film simulations?

Unless something changed in the last 6 months, the answer is no. Their demosaicing algorithm implementation for fuji still lead to the worms. You need to use capture 1 or dcraw/libraw.

It works for me - over sharpening produces worms but the denoise alone makes it worth it over Capture One for me.

The implementation used by libraw is just as good. Lightroom on the other hand is trash and wormy.
