Understanding the Adobe DNG Format
Jeff Schewe over at the impressive PhotoshopNews website has published a detailed look at Adobe’s DNG file format and how to fit it into your workflow.
“You get the benefit of knowing your proprietary Raw file formats have been converted to a fully documented Raw file format. You will probably see file size savings of 10-30% (or more, perhaps less). You have the ability to store not only the DNG converted Raw file but also embed, directly in the DNG a bit for bit copy of the original Raw file should you need it. You also get the benefit of having your Raw files stored with all your metadata embedded directly in your DNG file so you won’t need to worry about side car files at all. You get the potential benefit, depending upon the EXIF jpg thumbnail size in the original Raw file, of better performance inside of Adobe Bridge. If you shoot with multiple cameras possibly from multiple manufacturers, you also get the benefit of having all your Raw files in the same format.”
