I want to embed creator and copyright information in image metadata before publishing photos online. I’ve identified these fields:
- EXIF:
Exif.Image.Artist,Exif.Image.Copyright - IPTC:
Iptc.Application2.Byline,Iptc.Application2.Copyright
Are these the right fields to use, or should I add others as well? Also, do some services or apps favor certain metadata standards such as EXIF, IPTC, or XMP when reading creator/copyright information?

There certainly are thousands of tags to choose from, but it's not like you would put copyright in a tag for Aperture. There are only a coupled of standard EXIF tags that are relevant, and you've found them.
IPTC is a different metadata standard; you can fill those our too if you want. And, more modern software uses XMP, and there are even more fields there, allowing you to be more expressive — but EXIF is still the most common and I'd definitely start there.

Generated from our catalog & community — verify before relying on it.
For basic creator and copyright info, the EXIF fields you found are the standard ones to start with:
Exif.Image.Artistfor the creator/photographer nameExif.Image.Copyrightfor the copyright notice
The IPTC fields you listed are also appropriate if your software supports them:
Iptc.Application2.BylineIptc.Application2.Copyright
IPTC is a separate metadata standard from EXIF, so it’s common to write both. Many modern applications also use XMP, which provides similar fields and can be more flexible and descriptive.
So the practical approach is:
- Write the standard EXIF creator and copyright fields.
- Also write the matching IPTC fields.
- If available, add the equivalent XMP fields too.
There are many metadata tags overall, but for this purpose you do not need most of them. The main thing is to use the standard creator/copyright fields consistently across the metadata formats your tools support.
