DNG Tags

The main DNG tags are found in the EXIF table. The tables below define only information found within structures of these main DNG tag values.

DNG AdobeData Tags

This information is found in the "Adobe" DNGPrivateData.

The maker notes ('MakN') are processed by ExifTool, but some information may have been lost by the Adobe DNG Converter. This is because the Adobe DNG Converter (as of version 3.3) doesn't properly handle information referenced from inside the maker notes that lies outside the original maker notes block, and this information is lost when only the maker note block is copied to the DNG image. While this isn't a big problem for most camera makes, it is serious for some makes like Olympus.

The CRW data is from DNG-converted CRW images, but it has been restructured to a proprietary Adobe format (which results in a loss of the original hierarchical information structure, and creates extra work for everyone else who wants to use this information).
