In Lightroom, you do not save photos in the traditional
sense. Instead, you export photos. You can export photos
in a variety of file formats suitable for a wide range of uses.
For example, you can export photos as JPEGs to send in e-mail or
share online, or as TIFFs for a print publication.
When you export photos, you create new files that include Develop
module adjustments and other changes you’ve made to the photos’
XMP data. When exporting, options are available for specifying a
photo’s filename, color space, pixel dimensions, and resolution.
Export settings can be saved as presets for reuse.
The Publish Services panel allows you to export and upload JPEG
photos directly from Lightroom to photo-sharing websites. See Export from Lightroom to Facebook.
To export photos from Lightroom, follow these basic steps:
2. Export photos and choose a destination.
Choose File > Export or click
the Export button in the Library module. Choose Export To >
Hard Drive in the pop-up menu at the top of the dialog box.

The number of photos being exported appears at
the top of the Export dialog box.
3. (Optional) Choose an export preset.
Lightroom has several premade presets to make
it easier to export photos to disk in specific file formats. For
example, the For E-mail preset generates a small, low-resolution
JPEG image suitable for sending to a client as an e-mail attachment.
If desired, select any of these presets from the left side of the
Export dialog box and skip to Step 6. See Export photos using presets.
4. Specify export options.
Specify
a destination folder, naming conventions, and other options in the various
Export dialog box panels. For example, you can opt to add the exported photos
to the current catalog. See Export photos to disk or CD.
6. Click Export.
