I'm a amateur photographer that from time to time publish photos on various web sites for non profit.
I would like to add EXIF copyright information to each image so individuals/companies encountering my photos can see that they are not allowed to use/modify them for their own use.
Which EXIF tags should I use? According to this web site (this is also the tool I use to write EXIF) there is literally thousands of tags to choose from.
I have come up with the following tags:
Creator: (John Doe)
Copyright: (Copyright John Doe 2016)
Should I use different tags or additional tags?
I also wonder if search engines and apps (such as Google Photos, Facebook etc) favor certain tags when indexing photos. In that case it might be recommended to write information to these tags as well.
As @osullic pointed out, EXIF might not be the most obvious place to show copyright. But this question is only about EXIF data, as I know how to apply watermarks and copyright text overlays.
