rawspeed

Fujifilm lossy compressed raw still isn't supported after many years [1]. [1] https://github.com/darktable-org/rawspeed/issues/366 And in my experience there has been lots of bugs with Fujifilm raws in darktable: [2] https://github.com/darktable-org/rawspeed/issues/354 [3] https://github.com/darktable-org/darktable/issues/18073 However, Fujifilm lossless compressed raw actually does a decent job keeping the file sizes down (about 50% to 60% the file size of uncompressed) while maintaining decent write speed during burst shooting.

Ultimately, RAW formats aren't that complex, and camera firmware is mostly developed in countries that don't have strong open source software traditions. Look at the decoders for each format that darktable supports here: https://github.com/darktable-org/rawspeed/tree/develop/src/l... It's some binary parsing, reading metadata, maybe doing some decompression-- a thousand lines of C++ on average for each format. These aren't complex codecs like HEVC and only reach JPEG complexity by embedding them as thumbnails! Cameras absolutely could emit DNG instead, but that would require more development friction: coordination (with Adobe), potentially a language barrier, and potentially making it harder to do experimental features. Photographers rarely care, so it doesn't appreciably impact sales. Raw processing software packages have generally good

Take a look at the darktable docs: https://docs.darktable.org/usermanual/4.0/en/overview/suppor... The rawspeed lib is at github here: https://github.com/darktable-org/rawspeed

It looks like the ability to read the CR3 format may be available in freshly-compiled distributions of darktable soon, at least for some cameras. It relies on the exiv2 image library, which added support[1] for CR3 in v0.27.4. That said, there are some notes in the darktable issue[2] that suggest that the darktable rawspeed library also requires some updates[3].

As an anecdotal counterpoint, I'm a dedicated amateur photographer [1] who works entirely on a Debian stack (Darktable/GIMP). I've been occasionally curious about Lightroom/Photoshop's capabilities, but have never felt that I was lacking anything so grievous as to consider a switch. Furthermore, I'd have to run an entirely different OS from the one I've been using since 2002, and lash myself to a licensing model that would be both crippling and expensive. From my perspective, Adobe's tools do have remarkable capabilities and substantial support. The improved content-aware fill is remarkable, but I never need it. Adobe's close relationships with camera manufacturers (and large developer team) ensures that new cameras and lenses are supported almost at release. Lensfun and Darktable do a great job of keeping up with new hardware, but it oft
