I missed that one out. Try Exiv2::ExifTags::tagTitle(), I think this is
what you are looking for, although these labels may need tweaking.

Not sure which part you'd like to have automated, but I can't see
anything that Exiv2 could do for you here.
If anything, I suggest to decode the value only inside the if, i.e.,
only if you actually need it.
