Phil, I'm trying to copy EXIF and IPTC data from a tagged CR2 to a TIFF version. I'm using -tagfromfile and -all:all but there are tags missing in the TIFF. All IPTC values are missing along with 2 EXIF tags - Lens and LightValue.
Is there an additional option to copy IPTC values?
Not sure why these 2 specific EXIF tags are missing.
