[Digikam-users] Re: NEF/RAW+JPG: how to maintain coherent metadata

[Elle Stone]

Hi Julien,

I'm doing something similar to what Robert is doing. Except I've
decided to keep the raw files in the same directory as the jpegs. I
don't shoot jpegs along with my raw (cr2) files. Rather I use exiftool
to extract the preview image and save as a "sidecar" jpeg for each raw
file.

I use exiftool to write all the metadata from the raw file over to the
extracted sidecar jpeg. In digikam, I only write metadata to the
sidecar jpeg. And after using digikam to tag, write captions, etc for
the sidecar jpegs, I use exiftool to write the tags and captions back
over to the raw files.

Exiftool syntax is a bit complicated sometimes. I'm writing up my
procedure. When I'm finished (hopefully today), if you like I'll post
it for you to consult.

I can't compare exiv2 to exiftool, having never used exiv2.
Undoubtedly either will serve your purposes.
