I have thousands of photos scattered across several subfolders (but all of them are under a single parent folder). Most of those photos have values in their "Copyright" field, and that value differs from photo to photo.
Firstly, what I would like to do is to "cut" the value in the "Copyright" field, and "paste" it into the "Comments" field (a standard EXIF tag). I would like to this for all photos at once, and each photo has to keep its respective value (only now under a different category), of course.
Doing this photo by photo will take months - it's not an option.
Again, not all photos have a value in the "Copyright" field. Since manually selecting only the photo with value will also command a great deal of time, then I would like the process to simply ignore those photos without a value (or simply, "cut" an empty value and "paste" it - it makes no difference I believe).
Secondly, and after successfully doing the above, I would like to erase all EXIF information from all of those photos, BUT the "Comments" field.
Thank you so much.
