I am a big fan of the Dng raw file format. Dng files hold all of their metadata internally without the need for separate external .xmp sidecar files. I believe that is a huge advantage over the proprietary, camera-brand specific, raw files that my digital camera creates. In my workflow smarter files are worth the extra step that it takes to turn a camera brand specific raw file into a Dng raw file. Adobe Photoshop Lightroom makes this conversion, this re-wrapping of the raw sensor data, super easy.
In Lightroom, we can shift most any brand of raw file into the Dng wrapper at the front-door as we empty our memory card.
We can also convert raw files that are already in our Lightroom catalog over to Dng using the Library > Convert to Dng feature.
Finally, we can create a new copy of a raw file outside of Lightroom using the File > Export dialog and selecting the Dng file format.
Watch this tutorial video for more on the advantages of Dng and on how easy it is to use this advanced file format with Lightroom.
