![]() That might not seem like much, but when you are storing thousands of images on your hard drive(s) it can really add up.īelow is an example of two raw files compared to their DNG counterparts. However, when one of my raw files is converted to DNG, it is a whole MB smaller. My Nikon D700 raw files are around 11 MB, but newer cameras with higher megapixels create raw files that are 24 – 36 MB. Raw files are huge files, often being twice the size of their JPG counterpart. You can see below that the raw file has a. I edited both the NEF and DNG files (of the same image) in ACR. If you back up your raw files but not the sidecars, when you go to access that file you will only have the original raw data, not the edit, and you will need to re-edit. Why does that matter? With raw files, all your edits are in the xmp sidecar. xml files that are listed next to your raw files on your hard drive.ĭigital negatives do not require those sidecar files because the metadata is saved directly to the DNG file. Whenever a NEF or CR (or other camera brand raw files) file is edited in ACR, metadata sidecars are created to store the edits made. I circled the file name at the bottom, so you can see that it is a DNG file being edited in ACR. In the example, I opened a DNG in Photoshop, which made ACR open. ![]() ![]() A DNG opens just as a raw file you will see no differences there. This usually means through Adobe Camera Raw (ACR) or Lightroom, although some may use Aperture or other editing software. You edit DNG files exactly the same way you would a raw file. In other words, a raw file by Canon, a CR file, may have different data than a NEF file, which is a Nikon raw file. Each camera brand has their own format for collecting the data when an image is captured. I don’t want to beat you over the head and demand you starting converting your raw files to DNG files, but I do want to explain what a DNG is, then three things about them, to give you a taste of the cool-aid.įirst let me explain what a DNG is: DNG stands for Digital Negative and it is an “open source” format created by Adobe that effectively standardizes the raw data. Well, I definitely “drank the cool-aid” while I was there because I left being a firm DNG convert. You can always turn back to your favorite presets and LUTs, modifying them to meet the needs of the present, all while remaining in line with who you are as a professional.Last year when I went to Photoshop World I arrived knowing the basic concept of DNG file types but not really seeing the pressing importance of switching over to using them. They can even help you develop your voice as an artist-as you advance, you'll get a taste of what you like and what you don't.When the look is packaged neatly in this way, it can be shared easily between creative apps and collaborators, ensuring that everybody and everything remains on the same page aesthetically.LUTs can be used to address a myriad of technical problems and conversions, such as when converting from one color space to another.Those in narrative work or creating media for a professional brand always need to think about how what they put out there relates to everything that the audience has seen before. LUTs help you maintain consistency from shot to shot, scene to scene, and even production to production.If you're in the business of media creation, however, you already know that time is money.Ĭreating a new LUT from scratch every single time may be creatively rewarding, but there are so many reasons to consider automating some or all of the editorial process:
