I tried to make an account at https://redmine.darktable.org/login but still no activation email. I have a raw file free to use of a Canon EOS M5 that I would like to add in the darktable library http://www.filedropper.com/img0004_1
Would anyone with an account at darktable open a new issue for camera support?
I have already uploaded the raw file at https://rawsamples.ch/
Please keep in mind that redmine is the support method.
I did take a look, and not surprizingly, the camera uses different white levels for different ISO levels.
According to pdf usermanual, there is a M mode, where ISO can be manually set, is that correct?
If yes, please take one raw file per every iso setting that can be set, if possible including sub-iso.
And upload that to dropbox or something.
No problem.
You can also attach the raw files right here in the forum (up to 100mb). Just drag and drop it into the post composer.

The best file hosting that could find to upload from a phone.
You can upload from a phone here also.
900 MB in one file.
Thank you. I have a question you may be able to answer. With the older sensors from Canon (5DIII, 6D) ISO 320 is ISO 400 pulled with less noise and less dynamic range. ISO 500 is ISO 400 pushed with more noise and less dynamic range.
Do you know if it is the same thing with the new generation of sensors from Canon (M5, 80D, 5DIV, 1Dx II)?
No idea, sorry.
But if they still create those sub-ISO levels via digital push/pull, which is likely, i expect that it still results in the same noise and DR situation, not counting some improvements
Darktable 2.2.1 is out and support M5. Thank you
