Exiv2 starts writing metadata to Canon RAW CR2 files

Exiv2 starts writing metadata to Canon RAW CR2 files

Andreas Huggel released a major update to Exiv2, a free library and an application for reading and writing Exif and XMP image metadata.

Exiv2 is used by most advanced digital photography tools on Linux, including darktable and digiKam. The new version got write support for Canon's CR2 files and fixes to PNG and JPEG support.

Apart from that it now also reads metadata for a few more lenses:

  • Canon EF-S 18-55mm f/3.5-5.6 IS II
  • Canon EF-S 18-55mm f/3.5-5.6 III
  • Tamron SP AF 17-50mm F/2,8 XR Di II LD Aspherical [IF] Nikon lens

Additionally the support for Tokina 11-16mm f/2.8 on Canon was fixed, and the Nikon lens database was updated from Robert Rottmerhusen's fmountlens list.

As usual, source code and builds for Windows are available to download. Builds for Ubuntu will presumably land to Pascal's PPA soon.

  1. Writing to RAW files? Please, no. This is just wrong. Really wrong.

    Photo Mechanic has been doing it since dawn of times and not really failing :)

  3. Guess it’s nice to have the possibility, though I would only use it in “exceptional” cases (e.g. anonymising).

  4. This is *great* news!

    I would absolutely use metadata writing to raw files all the time. I use the files as the canonical version of the images, and since I want to store all metadata (tags, captions) inside the picture itself (so it isn’t lost) this is A+.

    I don’t have any Canon files though, but I was thinking about buying a Canon DSLR so I’d need support for that if I do.
