Hi,
I'm using exiftool 7.25 installed from MacPorts on Mac OS X 10.5.
I'm trying to copy exif data from a Canon raw file to it's jpeg counterpart :
$ exiftool -all= -TagsFromFile ../IMG_0093.CR2 -Canon -Canon:LensType --FileName IMG_0093.jpg
Warning: Can't convert value for Nikon:ShootingMode (no PrintConvInv) - ../IMG_0093.CR2
1 image files updated
As you can see, it triggers an error, and unfortunately -Canon:LensType won't copy at all. I'm also quite surprised I have to use "--FileName" otherwise, a new IMG_0093.CR2 is created in the current directory.
regards,
