Hi! I wanted to remove and add some exif data to some of my photos and I have found ExifTool. I've read the documentation on the website, but I have a problem... I want to remove all the EXIF data from my photos, except the fnumber (aperture), focal length and exposure time (shutter speed) and add a copyright information. I also want to apply this command to all my images at once! So I got stuck when I wanted to exclude the fnumber, shutterspeed and focallenght info... and the copyright information. Can someone please show me the exact command I have to use in order to remove all the information from the photos, EXCEPT the fnumber (aperture), focal length and exposure time (shutter speed) and also to add copyright info with my name. Thank you!
