Quoting Thom Hogan:
"there's this thing some DNG proponents keep trying to scare people with: "some day your camera maker might no longer support your raw format." So what? We already have open source code that interprets NEF (see libraw.org, amongst others). If the future some day will require you to move to another file format, you can do so then. In the meantime, for DNG to succeed the short-term benefits need to be bigger and clear. I don't believe they are."
