Copying from Raw to Extracted JPEG

[blue-j]

We're using ExifTool to extract the preview from raw files, and we'd like to copy relevant metadata from the source to the target.  Can anyone advise on best practice?  Will copying all be fine, or will that include fields that make no sense / are useless in the JPEG?

Thanks in advance for reflecting on this!

I would give this a try to see if it does what you want:

exiftool -tagsfromfile RAWFILE -exif:all -makernotes JPGFILE

Yes, some information may not be relevant to the JPG.

But note that previews may already contain metadata for some raw formats.

How might I omit a particular group?  Say, for example, I wanted everything copied but xmp-tiff.

exiftool -tagsfromfile SRCFILE --xmp-tiff:all OUTFILE

?

Exactly.
