Why is meta data 20 kb in a file
I was wondering why when saving metadata it adds 20kb in data. This seems quite a lot in file-size compared basically text.
attached are 2 test 1 with the meta-data 1 with. compare-mdata.zip
I noticed its not much text This is what i see in file info on photoshop for a file saved without Metadata
