I have a bunch of PNGs, which were sourced from scanned photographs with a creative-historical context. I converted them to JPGs so that I could write the
DateTimeOriginal tag to them using ExifTool through ExifGui. I created
DateTimeOriginal tags for the PNGs from the preexisting
FileModifyDate tags en masse.
I can successfully copy metadata from PNGs to JPGs with
DateTimeOriginal intact from a PNG file to one JPG file at a time using the following command.
exiftool -tagsfromfile file.png file.jpg
However, I want to copy metadata from PNGs to JPGs en masse.
I am an amateur photographer that uses ExifGui primarily for giving files
DateTimeOriginal tags, so I don't have a good grasp on what most commands do. I have tried looking elsewhere, but I have not found answers and I am not patient enough to look through the documentation. Is there a way to copy metadata from a group of PNGs to JPGs if only their file extensions are different using variables or similar?
