Will 3.6 be able to read cr3 files from a R5?

In the respective darktable issue on github it also says dual pixel as well. Do you also want that? I guess if yes, we’ll have to do this in several steps as my poor server is not that big :smiley:
Currently uploading raw and craw

@johnny-bit

I’ll do that tomorrow Hubert, I’m happy to help!

@johnny-bit Please find R5 raws, cropped raws, craws, cropped craws, dual pixel raws, cropped dual pixel raws, dual pixel craws and cropped dual pixed craws here:
https://pandainthecloud.de/nextcloud/index.php/s/qwFEYQrzHqPBgQk
Taken with firmware 1.3.1

I’m sorry if the naming conventions are not fulfilled 100% but renaming after downloading seemed easier than reuploading several hours again.

Hope this helps!

Also please let me know when you dont need the files anymore on my server

put them to https://raws.pixls.us

The prolem with raw.pixls.us is that it’s 1 sample per camera mode (not iso setting) and base iso is assumed.

AFAIK we need full set of ISO samples for black levels difference.

Other that that raw.pixls.us is an amazing resource that needs to be used :slight_smile:

For the ones not following development closely there is now an intial cr3 parser/decoder Support for Canon CR3 raw files by cytrinox · Pull Request #271 · darktable-org/rawspeed · GitHub

I am happy everything is moving so fast :slight_smile:

Hubert I’ll reply in the other thread with the links to get all the samples you needed. I’ll also see if I can upload all of these files to raw.pixls.us?

Ideally upload to raw.pixls.us JUST the base ISO. Currently the only “missing” differentiation on raw.pixls.us is ISO setting. That’s why I’m asking for links to pack of files. Those WILL end up on raw.pixls.us if the sample set of base ISO is missing on raw.pixls.us

ok just tried but raw.pixls.us refuses my shots as “they’re already here”.

I’ll keep them on my disks anyway. (it was a nice escapade this morning to set up a “natura morta” to do those shots).

It’s not just about the R5 - RAW files from all modern Canon Cameras (CR3) are now unsupported. Very sad.

What are you talking about?

We are working together to make it happen. Those not into darktable development rn provide raw samples to get camera support done earlier. Code is being written as we speak so I am very optimistic. You can also provide raw images and white balance profiles if your camera is not yet supported. See:

Progress: Support for Canon CR3 raw files by cytrinox · Pull Request #271 · darktable-org/rawspeed · GitHub

So happy about this!

I’m now very undecided on which way to go;

  • Convert all my past cr3 files to dng, import them in dt and start working them, adding metadata etc straight away or
  • Wait for cr3 support to be implemented in source

I need to investigate if the first option allows me in the future to simply substitute dng for cr3 files and preserve processing, metadata etc…

I would not convert to dng and expect it to be easy to sub in the cr3.

You can build master now, import, and start editing, then just stick to stable when that is released.

And while you are at it, @aadm, create a noise profile for the RP. If you need help, I can offer some newbie guidance to the process as I did it myself the last days for the first time :smiley:

There’s a bit more to it than simply building master to get CR3 support working:

  • you need to pull down rawspeed PR #271 before building darktable
  • you need to update your exiv2 to 0.27.4-RC2 and build it with EXIV2_ENABLE_BMFF=ON
  • you may need to put a standard matrix for your camera into adobe_coeffs.c if it is not already there.

then if you build master, you should be able to open CR3 files. Some features like lens corrections, denoise profiles and WB presets may not be there yet, but that’s being worked on too.

So, CR3 support is not quite yet ready for production use, but it’s getting very close.

oh definitely! if you can give me some guidance I’ll do that (noise profile I mean).

So I can finally feel like I’m contributing something!

Thanks Matt. All these things sound maybe a bit too complicated… I’ll probably just wait a little and maybe help with noise profile for the RP for now.
