[QUOTE="Brian, post: 251165, member: 17621"] DNG is based on the TIFF 6.0 standard, also written by Adobe. TIFF 6.0 has a lot of features that have not been implemented by most software packages, including the ability to store multiple images in one file. Almost 20 years ago my wife ran into that problem with a Microscope camera that placed all of the images from a session into the same file, but the software packages used to process the files could not handle it. My "Honey-Do" list was to write software to convert TIFF 6.0 multi-image file to a set of TIFF 6.0 single image files. Easy- because the documentation was published. DNG is a published specification. I can use my new cameras with software that came out years ago, before the camera was introduced BECAUSE the file format is written to a standard. With NEF- you have to wait for the software publishers to get the new file format under a developer's agreement with Nikon and update the software. Means always running back to get an upgrade, and most often- pay for a new version. Or write your own software and be good at parsing through files that don't have a published spec. Sometimes you get lucky. Hacking Df files to be processed by LR4 took 20 minutes. You can usually find enough info once it's in DCRAW. Until he gets tired of updating it. [/QUOTE]
