PHOTOSHOP LIGHTROOM 43 User Guide Convert photos to DNG Lightroom lets you convert camera raw files to DNG for archiving and taking advantage of DNG features. When photos are converted to DNG, the DNG files replace the originals in the catalog. You have the option of deleting or preserving the originals on disk after the conversion. 1 With photos selected in the Grid view, or with a selected photo in Loupe, Compare, or Survey view, choose Library > Convert Photo(s) To DNG. 2 In the Convert Photo(s) To DNG dialog box, select any of the following conversion option: Only Convert RAW Files Ignores photos that are not camera raw files. Deselecting this option converts all selected photos, including JPEGs, TIFFs, and PSDs. Delete Originals After Successful Conversion Deletes the original photo file after the conversion process ends. Deselecting this option preserves the original file on disk. File Extension Choose whether the file extension is .dng or .DNG. JPEG Preview Choose whether the exported JPEG preview is full sized, medium sized, or not created. Image Conversion Method The image data is stored in the original "mosaic" format, if possible, which maximizes the amount of data preserved. Mosaic data can be converted to linear data but the reverse is not possible. Choose Preserve Raw Image to store the mosaic data. Choose Convert To Linear Image to store the image data in an interpolated ("demosaiced") format. The resulting image can be interpreted by other software even if that software doesn't have a profile for the digital camera that captured the image. Compressed (lossless) Choose whether to use lossless compression, meaning that no information is lost while reducing the file size. Embed Original Raw File Choose whether to store all of the original camera raw data in the DNG file. See also "About file formats" on page 17 Open a file in Explorer or Finder ❖ Select the photo and choose Photo > Show In Explorer (Windows) or Show In Finder (Mac OS). The file is selected in an Explorer or Finder window. Create virtual copies You can have multiple versions of photos by applying different adjustment settings to virtual copies of the original (master) photos. Virtual copies don't exist as actual photos, but are metadata in the catalog that store the different sets of adjustments. You create a virtual copy of a photo and then apply adjustment settings to it. If you want another version of the master photo, you create another virtual copy and apply the new settings to it. You can create as many virtual copies of a master photo as you wish. You can even make one of the virtual copies a master, making the previous master a virtual copy. Once created, virtual copies are automatically stacked with the master photo. In the Grid view or the Filmstrip, the master photo displays the number of images in the upper-left corner of the thumbnail. The virtual copies display page-turn icons on the left side of their thumbnails.

With photos selected in the Grid view, or with a selected photo in Loupe, Compare, or Survey view, choose
Library > Convert Photo(s) To DNG.

In the Convert Photo(s) To DNG dialog box, select any of the following conversion option:
Only Convert RAW Files
Ignores photos that are not camera raw files. Deselecting this option converts all selected

Image Conversion Method
The image data is stored in the original “mosaic” format, if possible, which maximizes
the amount of data preserved. Mosaic data can be converted to linear data but the reverse is not possible. Choose
Preserve Raw Image to store the mosaic data. Choose Convert To Linear Image to store the image data in an inter-
polated (“demosaiced”) format. The resulting image can be interpreted by other software even if that software doesn’t
have a profile for the digital camera that captured the image.
