No metadata for CR3

[Andrew Rabert]

Version: 1.8.2, Arch Linux

What: Metadata is not displayed for CR3 files.

Example file is attached.

Thoughts

It appears that ART is using code from an older version of libraw which lacks changes metadata related changes added on Jan 22 2021. https://github.com/LibRaw/LibRaw/commit/4c954948ba2de262b9cb23a1843fb8651aa3dcc1#diff-93da3259824f38be9855edb6a759cfc2e18097f4405211e756653c38fadf9462R293-R298

hi,

You need to use a recent version of exiftool and make sure that art can find it. See also here: https://garridodiaz.com/canon-cr3-support-in-linux-using-art-rawtherapee-clone/

Ahh, that fixed it. I’ve notified the AUR maintainer to add perl-image-exiftool to optional dependencies of ART.

Thank you

Followed the above instructions (https://garridodiaz.com/canon-cr3-support-in-linux-using-art-rawtherapee-clone/), but the issue still remains on Ubuntu 20.4

Hi, can you share a raw file? Also, can you try using the latest version (i.e. 1.8.2)?

[The Wanderer]

Version 1.8 works perfectly, previously I installed it via PPA/APT which has the version 1.2 only, they are usually a bit behind.

For some reason the link to download the 1.8 packages here (https://bitbucket.org/agriggio/art/downloads/) does not work in some locations (for example in Turkey where currently I reside), had to resort to a VPN connection to be able to download.
