Hi

When I crop a Canon Ixus v2 photo and save it (Ctr+S), Photoshop CS only keeps standard exif information. It erases all exif information specific to Canon. So I need to use another tools (ExifUtils) in order to rewrite the complet exif information.
Is it possible to prevent Photoshop from deleting vendor exif information?

Thanks
