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.

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.
