Save metadata changes to a file manually

To manually save metadata changes to a photo in Lightroom Classic CC, do one of the following:

• Select one or more photos in the Grid view of the Library module and choose Metadata > Save Metadata To File(s), or press Ctrl+S (Windows) or Command+S (Mac OS).
• Click the Metadata File Needs To Be Updated icon in a thumbnail in the Grid view of the Library module, and then click Save.
• If you’re working with a DNG file, choose Metadata > Update DNG Previews & Metadata to save metadata changes to the file and also generate a preview based on the current raw processing settings.
