Black and White in Photoshop CS4 and Photoshop Lightroom IV. Export: Archive, Contact Export DNG and burn another backup After all the image processing, file naming, keywording, copyright embedding, sorting, ranking and global adjusting has been applied to your satisfaction, the best practice would be to burn another backup onto disk. Lightroom offers the option of burning large JPEGs to disk with one quick and easy step (great for registering copyright of your images). Since the raw files are your "digital negatives" containing the highest quality versions of information, the best practice will always be to do everything you can to save them. I first export all the images as DNG files with all my latest editing and adjustments to a separate folder as "selects" for backup and burn that file to DVD. Step 1: In Lightroom, click the big Export button at the bottom left panel of the interface window, or go to the File Menu Export. The Export dialog box will appear. As always, the top down approach is the most logical and effective way to address dialog boxes within both Photoshop and Lightroom.
