If the photograph is copyrighted, how does this modification and embedding of tracking data by a third party affect the owner, if it does at all ?
I ask what is the legal situation for a copyright holder, given users likely are not aware of this data being added to a file; what the data exactly is, where or if this data is kept by them independently of the file itself, what is it used for, GDPR implications, etc.
So if the images is converted to digital form, then compressed then decompressed, then printed out then usually it would be considered the same image.
