I’m sorry to hear there’s so much difficulty with implementing CR3 into Darktable. Frankly, I would have expected Canon to be more supportive given that holding off could dampen sales. I shoot Canon and might migrate toward mirrorless at some point, and incompatibility with Darktable might lead me to a different company.
Any rate, I did follow the OP advice and reached out to Canon, who sent me the following response:
Thank you for contacting Canon product support. I understand you are inquiring if Canon will provide the CR3 format specifications to the developers of the Darktable application. My name is Jacob and I’d be happy to address your inquiry today.
Unfortunately, Canon does not provide the CR3 format specifications to application developers. Developers, like Adobe, will update their software after studying and reviewing the CR3 file format. You would need to reach out to the developers of Darktable for further assistance. I do apologize for the inconvenience.
Please let us know if we can be of any further assistance.
Have a great day.
Thank you for choosing Canon.
Sincerely,
Jacob
Technical Support Representative
This may be helpful or not, but I’m just offering this as a data point from a DT user and it would seem the question is moot at this point, anyway
Thank you to all the developers for all of your work. Your effort is greatly appreciated even if it may not seem that way at times.
