EXIFtool can manipulate EXIF headers, but can it create EXIF headers for images which are missing EXIF header as a whole? If so, what is the syntax?
To further clarify, how do you add EXIF data to images which have no EXIF data at all? Not empty EXIF headers, but no EXIF headers at all.
exiftool -EXIF:ExposureTime=1/200 file.jpg) to a file that is missing the EXIF header? Do you get an error? Please [edit] your question to include what you've tried so far, and what brought you to the conclusion that the header is missing. – Saaru Lindestøkke Dec 08 '21 at 16:14
