As these demosaiced DNG files are no longer truly raw, do not delete your original raw files! This procedure is merely a workaround.

Though you cannot directly process these raw files in RawTherapee, you can convert them to demosaiced DNG files using the Adobe DNG Converter. Some cameras have sensors with color filter array layouts and sensor pixel layouts unsupported by RawTherapee. While this is generally undesirable, there are situations where we can take advantage of this possibility. These demosaiced images are no longer really raw - they have been pre-cooked. The DNG format can contain real raw data, but it can also contain demosaiced images. These DNG files are no longer really raw due to them being demosaiced, and in doing so you are relying on Adobe's demosaicing algorithms and can no longer benefit from using RawTherapee's demosaicing algorithms, so do not use these settings for raw files which are natively supported by RawTherapee.

Download Adobe DNG Converter (get the build for Windows if you're using Linux - installation is explained below).Īdobe DNG Converter 8.3.0 set up to convert raw files to demosaiced DNG files.

Having said that, issues with DNG are very rare, unlike the FUD surrounding it which is in no hurry of dying down.Īdobe's DNG Converter is not the only program that converts raw files to DNG. If you do convert your raw files to DNG, you should first test a few sample DNG files to make sure everything in your workflow still functions correctly before deleting the source files. Possible reasons could be that the newer color matrices might be more accurate, lossless compression might be improved, improved support for defective pixel marking, inclusion of new opcodes, injection of new useful metadata tags, etc. In some cases it may be warranted to re-convert your old DNGs to a newer DNG specification using the newest version of Adobe's DNG Converter.

Even if your camera supports shooting straight to DNG, your camera's implementation of DNG is likely outdated.

Computer software does not have this limitation. The camera software is limited by its hardware - it must write the raw file as quickly as possible and not draw too much current, so compression is optimized for speed, not for file size. DNG files are often smaller than your original raw files due to better lossless compression.This leads to more accurate color and lowers the chance of color casts in clipped areas. Adobe's DNG Converter includes color matrices and white levels in the converted DNG files - these are usually not present in non-DNG files, and Adobe's ones are often more accurate than those from dcraw.It is not a dead format - it is constantly maintained.You may be able to use your DNG images in programs which do not have support for your non-DNG raw format. There are numerous benefits in converting your raw files to the DNG format: Unlike JPEG images, which are already "developed", these raw files (both proprietary and DNG) contain raw data (ergo the name "raw file" - do not capitalize it, it is not an acronym!) which must first be processed before an image is obtained. Some cameras also let you choose DNG (Digital Negative) as the raw format, which is an open, lossless format developed by Adobe. The "Linear (demosaiced)" option must be not selected in order to convert raw files to raw DNG, otherwise the DNG will contain an already-demosaiced (non-raw) image.ĭigital photography cameras can most often save your images in the JPEG format, as well as dump the raw values from each of the millions of photosites which make up a sensor and store them, along with some metadata, in a proprietary raw format.
