Cannot import CR3 files from new Canon EOS R5 MarkII

Software ART
1

Hello, I just bought the new EOS R5 MarkII from Canon and it looks like they once again changed something in the CR3 file format because when I try to open them In ART I get this :

Copie d'Ă©cran_20240825_110534
Copie d'Ă©cran_20240825_1105341920Ă—1200 2 MB

Any idea somebody ?

Thanks in advance !

Hi,
the camera model is not yet supported by the latest publicly available version of libraw. It is supported by the latest beta version of rawdigger, so hopefully things will change soon (but I don’t know when…).
In the meantime, you can get something slightly better by adding this entry to the file $HOME/.config/ART/camconst.json:

    {
        "make_model": "Canon EOS R5m2",
        "raw_crop" : [ 272, 176, 8190, 5464 ],
        "ranges" : { "black" : 512, "white" : 16382 } 
    }

If the file doesn’t exist, just create it with this content instead:

{"camera_constants": [
    {
        "make_model": "Canon EOS R5m2",
        "raw_crop" : [ 272, 176, 8190, 5464 ],
        "ranges" : { "black" : 512, "white" : 16382 } 
    }
]}

A few caveats though:

  • The above black level seems to work for ISO 100, but I don’t know if it works for other ISOs
  • WB and input colour profile will still be off

Anoter option might be to convert to DNG with the Adobe DNG converter (I haven’t tried that though).

Thank you very much for this info.
I will try

Have a nice day !

If that solution doesn’t work you could use a DNG converter such as Adobe’s which is free to get any unsupported RAW file to then open in any editing program.

also if you want to modify libraw yourself, that’s whats neccessary. Works fine in darktable for me at least:

Hi,
I’ve added some basic support for the R5mk2 (and the R1) to the current master. You need also the latest version of exiftool for white balance to work properly.

Hello, thank you very much for keeping me informed. I’ll install it very soon !

Well, I’m afraid I don’t know what to do with these files :roll_eyes:
Any help would be much appreciated :pray:

Which files are you talking about? What OS?

10

I was talking about the master files from Alberto. I run Linux Manjaro.
Sorry, I should have specified

11

If you want to use the AUR: AUR (en) - Packages

Otherwise you’ll have to build from source.

12

Tank you. Already installed on my Manjaro. What I need is the last update from Alberto 4 days ago. And I don’t know how to install or build it

13

Install the -git package. That will get you whatever is in git master. But be aware that not all aur helpers may know how to keep it updated automatically, since the pkgbuild will only rarely change version.
