How Do I Fix Photo Dates From a Memory Card?
Camera photos usually have correct dates already. Check before fixing anything.
Photos straight from a camera almost always carry a correct Date Taken, because the camera wrote it at the moment of the shot. Copying them to a computer changes the file dates but not that one.
So check before changing anything. If Date Taken is right, the only job left is naming and sorting, not fixing.
Takeout JSON Metadata Fixer reads the existing date and uses it, rather than overwriting a good value with a worse one. It runs on your own computer and is free for your first 500 photos.
