I recently purchased a Canon T2i and found that the CR2 files for the newer camera are different than the CR2 files made by the older Canon XSi.
Just recently Aperture 3 came out with an update to their software to read the new CR2 file format. I've tried to use Houdah to gain access to those files from Aperture and I get a couple of errors.
First, when I point to the folder in the Aperture library the files get imported with a JPG ending not with the CR2 raw ending (all the photos were raw and not jpeg so this was an error). I tagged these files anyway but when I attempt to write to the EXIF I get a popup error message for each photo similar to:
Failed to tag image: IMG_xxxx.jpg (where x's are obviously the image numbers).
So the changes to Aperture to accomodate the new CR2 files are somehow not working with Houdah.
If I copy the pictures to a separate folder (not in Aperture library), Houdah can tag them fine and then I can import them into Aperture with geotagged data.
The issue just appears to be between Houdah getting files from the updated Aperture 3 library.
