Re: can't figure out how to copy some tags from a CR2 to the corresponding JPEG
It sounds like you should be copying lenstype to xmp:lens if
that is all you want. You cant delete individual makernote
tags. And sorry there is no hierarchical tag name documentation,
just the TagName web pages. - Phil
