I am using -j -struct options to get the tags in JSON format. What groups should I use to prevent duplicates from being excluded in the output? I assume -G:0:1 is not enough?
From the docs on the
-j (
-json) option (https://exiftool.org/exiftool_pod.html#j-JSONFILE--json)
QuoteThe -a option is implied when -json is used, but entries with identical JSON names are suppressed in the output. (-G4 may be used to ensure that all tags have unique JSON names.)
