PosingPosing Have your tried or wondered about the DNG format? DNG is also considered to be a RAW image file. It is Adobe's image standard that was created to store image data in a generic, highly-compatible formatTypically RAW files are specific to a camera brand such as Canon (CR2) or Nikon (NEF). 

It is so compatible that the ASMP and the US library of congress have recognized this as a preferred method of storing files over long periods

time without needing a specific camera software to decode the file(s).

One of the primary advantages of the DNG format is that it saves space when archiving files. In most cases it can save 15-20% when compared to the file or a brand specific RAW file. Depending upon how much ones shoots, even 15% can be significant particularly if you make multiple backups of your images. Although by default, a JPG preview is included in the format, that can be deleted making the files even smaller.  

Unlike Raw formats, DNG does not require a sidecar xmp file to store changes,since changes are written directly to the file. This makes life just a little easier when trying to manage large numbers of files.

Adobe Lightroom can easily convert from Raw to DNG and adobe also  distributes a free DNG converter.  Since this is an open source format,  developers have the ability to incorporate it into other applications with some slight modifications. 

There are some compatibility problems with this format with the Program "Capture NX" and in some rare cases it may strip out some unrecognized metadata.

Give DNG files a look the next time you are planning a second backup for you images. You may be pleasantly surprised.
