The most foolproof way to hide the EXIF data from the viewer is to select the entire image, copy it, then paste it into a new image file, thus stripping the EXIF data. There are a few freestanding EXIF utilities, such as ExifTool, that will let you change the EXIF values. Both Media Pro and Lightroom offer tools to strip all EXIF. Finally, I should note that my viewer makes use of Phil Harveys most excellent Image::ExifTool library.
With a few exceptions, EXIF data is not editable in Photoshop or other DAM software, although it can often be stripped entirely from the file. Many have their Exif data stripped, but many do not. Lens Make : Apple Lens Model : iPhone 5s back camera 4.15mm f/2.2 GPS Latitude Ref : North GPS Latitude : 33.055130° GPS Longitude Ref : West GPS Longitude : 96. This might be because you consider your technique to be a trade secret or because you don’t wish to reveal information about exactly when the photograph was made. Once exported with location metadata, exiftool -groupname file will show you just what you expect to see. There are times when you might not want to share the camera-created information with the world. This is a very difficult situation to sort out and is probably best approached using the program ExifTool or PhotoMechanic (assuming you really want to go there.) Of course, it can also lead to data mismatches if the native EXIF and the XMP version aren’t identical.
This duplicate of the EXIF data can make it easier for other programs to read since XMP is written in a standard way.
When Adobe Bridge sees a file with EXIF data, it pulls out everything it can understand and writes it as XMP metadata to the file or sidecar file.
