OpenRAW - Digital Image Preservation Through Open Documentation aims to focus on open documentation (and promoting this with manufacturers). This is an important topic, especially in light of Nikon's stupid decision to encrypt parts of the RAW format (thus ultimately making its use in free software legally problematic due to the need to crack the copy protection). I've already written about this: the digital negatives belong to the photographer, not the camera manufacturer. Everything must be done to provide the photographer with all the information contained within - without any encryption nonsense and without the obligation to use any silly manufacturer programs (which, in the worst case, are not even available for the operating system used).
An interesting parallel is drawn on the website: can anyone imagine that film manufacturers would have kept the data for film development secret? That Agfa or Kodak or whoever else would not have provided development documentation with their films, allowing the photographer to develop the film themselves?
Nikon's attempt to control and regulate RAW software and dictate what a photographer can do with their image data is similar to this stupid approach. And hopefully - if necessary through the market - doomed to fail. Because if this way of thinking were to prevail, we would eventually have digital negatives where the camera manufacturers dictate how many prints we can make from our own image ...
