Hi Phil,
Is it possible to force output of every EXIF field exiftool is capable of extracting, even if some of the files being processed don't have values for every field?
I'm doing a comparison of two batches of images. A lot of them have X number of populated exif fields, while others have Y populated fields. I'd rather end up with a CSV that has every single EXIF field.
Thanks!
BTW, I should've said "every metadata field exiftool is capable of extracting" and not just EXIF. ;)
You an force exiftool to output all specified tags, even if they don't exist, with the -f option. This option, however, will not output all possible tags (that would be an immense number...), just the ones you specified. I suggest you create a list of tags you'd like to see and work with that. You can list the tags exiftool is capable of extracting with the various list options.
Hope this helps,
Hayo
The number of pre-defined tags is currently around 19000, but ExifTool also extracts tags that are not pre-defined from some metadata types. So it is not possible to do what you ask.
