Subject: | CanonVRD tags written by Canon codec are not readable Exiftool |
I discovered this issue using Windows Live Photo Gallery with latest
Canon RawCodec v.1.7.0.56.
1. Install Canon RawCodec on Win7 x86 or x64.
2. Install Windows Live Photo Gallery from download.live.com
3. Run Windows Live Photo Gallery. Navigate to any of CR2 files.
4. Set Rating, add descriptive tags, Caption, Author, and or Geo
tag.
5. Canon codec writes those updates to cr2 file under CanonVRD
trailer.
6. Try to see what’s in CanonVRD: exiftool.830.exe –canonvrd
Result: “Canon VRD : (Binary data 1453797 bytes,
use -b option to extract)”
“exiftool –canonvrd:all” shows nothing too.
WicExplorer can see retrieve those values:
