I created a better checkerboard detection algorithm written in Python!
A major problem with intrinsic calibration is the lack of open source libraries that can accurately detect highly distorted, high density checkerboards. OpenCV and other surface level detection libraries are pretty much unusable for anything other than low density checkerboards. MATLAB has a great package, but it is obviously closed source and is pretty slow. Libcdetect is okay, but there are only versions written in MATLAB and C++ (and I have no idea how to use C++ haha. Let me know if you know how to use this C++ package!).

Support for a6700?
It works fine in the latest stable release of Darktable. You just need the definition for the camera in cameras.xml. Support for the A6700 was already added in the development branch but there hasn't been a new stable release yet since. Fortunately, simply downloading and replacing the file (which you can get from the dev branch on GitHub) suffices.

How about this? https://github.com/darktable-org/rawspeed/blob/develop/data/...

Support for Nikon Z8
Propably you can just download cameras.xml and replace the one you locally have https://github.com/darktable-org/rawspeed/blob/develop/data/cameras.xml

A7R V RAW Support
As /u/emkoemko said, support for lossless compressed RAW is not available at this time. The support of Sony lossless RAW in darktable depends on rawspeed implementing support for it. You can follow and contribute to the effort here: https://github.com/darktable-org/rawspeed/pull/386

darktable feature release 4.0.1
Does anyone know what's the way to help with the OM-1 camera support? There's a PR that works really well (https://github.com/darktable-org/rawspeed/pull/357).

[REQUEST]: I need some examples of Canon RAW format files or a utility to make them.
The repo of files used for RAWSpeed (https://github.com/darktable-org/rawspeed)
- Upgraded from 2.6.2 to 3.6.1 - Images now tend to be very pink or very green, even after clearing history stack

Next release
No samples on https://raw.pixls.us/ it seems. If you provide samples and open an issue in the rawspeed issue tracker this will make things a lot easier https://github.com/darktable-org/rawspeed/issues

dng files from smartphone look dark and dull.
For some references, see for example DT PR, DT issue, and librawspeed issue.
