DNG History and Summary

Barry Pearson has recently posted a number of blog posts outlining his experience learning and writing about the DNG format since it was introduced. They’re an excellent resources so I’ve added links/summaries to his posts below.

DNG Part 1 – Seven years of writing about Digital Negative Format
This article provides the background on all of the material Barry has written on the DNG format

DNG Part 2 – Timeline for the Digital Negative Format
The timeline of major DNG announcements is covered as well as this interesting tidbit:

“During the first 5 years when about 38 camera models were launched that wrote DNG, Adobe software added support for about 21 Canon models, about 20 Nikon models, and about 22 Olympus models. Camera models that write DNG are almost certainly launched at a much higher rate than camera models that support any other individual raw image format, including NEF, CR2, and ORF.”

DNG Part 3 – The tragedy of OpenRAW
The story of the OpenRAW initiative

DNG Part 4 – DNG is the ONLY archival raw file format
Barry outlines the value of the DNG format

I’d like to thank Barry for putting these articles together, summarizing his tireless efforts over the years to document and chronicle the progress of DNG.

    < except that market share of those cameras is dropping and dropping…

    Too bad that:

    1. the DNG SDK has a license that is not clear, unlike the XMP SDK, and that make it incompatible with several popular open source license. – I had requested this change eons ago but never heard anything back nor seen any change.

    2. the conversion from non to DNG to DNG is kept secret and not included in the above SDK. If DNG was meant to be an archival format this recipe would be part of the SDK, as published source code and/or documentation.

    And this is something Adobe could lead the charge with.

    Hub, please elaborate on the 1st request, as the second one is self-explanatory.
    There is also http://feedback.photoshop.com to make such suggestions, and get the ears of the Adobe engineers (but reaching those of the PM is not a bad thing either ;) ).
