preference settings in the Auto Import Settings dialog box (see "Importing automatically" on page 25) and in the
Catalog Settings dialog box (see "Change catalog settings" on page 33).
1 From the Lightroom main menu, choose Edit > Preferences (Windows) or Lightroom > Preferences (Mac OS).
In the Import preferences, do any of the following:
2
• To allow the import dialog box to be opened automatically after connecting a camera or memory card reader to
your computer, select the Show Import Dialog When A Memory Card Is Detected option. If this option is not
selected, Lightroom does nothing when a camera or memory card is connected. (You can still choose File > Import
Photos From Device.)
• To not use the folder names that your camera creates, select Ignore Camera-Generated Folder Names When
Naming Folders.
• To import duplicate JPEG files and raw files separately, select the Treat JPEG Files Next To Raw Files As Separate
Photos option. Deselect this option to import only a single file.
• To specify how DNG files are imported, specify options in the DNG Creation Settings section. For more infor-
mation on DNG files, see "Convert photos to DNG" on page 43.
3 In File Handling preferences, do any of the following:
• To determine how periods and forward slashes are used to separate keywords, select options in the Reading
Metadata area.

they're replaced, choose from the menus in the File Name Generation area.

About file formats
Lightroom support the following file formats.
Camera raw formats
Camera raw file formats contain unprocessed data from a digital camera's sensor. Most camera manufacturers save
image data in a proprietary camera format. Lightroom reads the data from most cameras and processes it into a full
color photo. You use the controls in the Develop module to process and interpret the raw image data for your photo.
For a list of supported cameras and camera raw formats, see www.adobe.com/go/learn_ps_cameraraw.
Digital Negative format (DNG)
The Digital Negative (DNG) is a publicly available archival format for raw files generated by digital cameras. By
addressing the lack of an open standard for the raw files created by individual camera models, DNG helps ensure
that photographers will be able to access their files in the future. You can convert proprietary raw files to DNG from
within Lightroom. For more information about the Digital Negative (DNG) file format, visit www.adobe.com/dng.
