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 (https://exiftool.org/exiftool_pod.html#tagsFromFile-SRCFILE-or-FMT) 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/
Thank you! Appreciate your prompt response.
