Selective Bulk Delete of Metadata by Standards

[jfarkas]

Hi,

What is the most effective way delete metadata by standards?  For example, how woudl you approach a scenario if someone wants to keep all IPTC and PLUS fields but delete the rest?

You would basically clear everything then use the -TagsFromFile option to re-add the stuff you want to keep.  One common example I see often is to remove everything but keep the Orientation
exiftool -All= -TagsFromFile @ -Orientation /path/to/files/
