Managing catalogs and files
Last updated 4/20/2015
Automatically Discard 1:1 Previews This setting specifies when 1:1 previews are discarded based on the most recent
access to the preview. 1:1 previews have the same pixel dimensions as the original photos, and show sharpening and
noise reduction. They are rendered as needed and can make the catalog preview file large, so it's good to discard
them periodically.
Smart Previews Indicates how much disk space is being used by Smart Previews. For information on using Smart
Previews, see Smart Previews .
Import Sequence Numbers Specifies starting sequence numbers for photos as you import into the catalog. Import
Number is the first number in a series that identifies how many import operations are performed. Photos Imported
is the first number in a series that identifies how many photos have been imported into the catalog. See
The Filename
Template Editor and Text Template Editor .
4 In the Metadata tab, select any of the following:
Offer Suggestions From Recently Entered Values When you start typing a metadata entry that resembles a previous
entry, one or more suggestions appear as you type. Deselect this option to turn it off. Click Clear All Suggestion Lists
to clear previous entries.
Include Develop Settings In Metadata Inside JPEG, TIFF, PNG, And PSD Files Deselect this option to prevent
Lightroom from including Develop module settings in the XMP metadata of JPEG, TIFF, PNG, and PSD files.
Automatically Write Changes Into XMP Select this option to save metadata changes directly to the XMP sidecar files,
making the changes visible in other applications. Deselect this option to save metadata settings only in the catalog.
For information on saving XMP changes manually, see
About metadata and XMP .
Enable Reverse Geocoding of GPS Coordinates To Provide Address Suggestions Allows Lightroom to send your
photo's GPS coordinates, if available, to Google so that Lightroom can determine the city, state, and country of the
photo and add that information into the IPTC Location metadata.
Export Reverse Geocoding Suggestions Whenever Address Fields Are Empty If selected, Lightroom includes
Google-suggested IPTC Location metadata in photos when you export them.
Write Date Or Time Changes Into Proprietary Raw Files This option controls whether Lightroom writes a new date
and time to proprietary raw files when you use the Metadata > Edit Capture Time command to change a photo’s
capture time metadata. By default, this option is not selected.
Optimize the catalog
After you have imported, edited, and perhaps removed a number of files, you may have to wait a significant amount of
time while working in Lightroom. When that happens, optimize your catalog to improve performance.
❖ Choose File > Optimize Catalog.
