As I understand it: * Canon only uses encryption on critical info to the demosaic on the Powershot models. * Adobe has permission from several manufacturers to decrypt . Beyond that, the Nikon trend is very clearly towards more and more obscuring of critical data, and at some point they cross a line and need to be called on it. The D2x crossed that line.

Beyond that, the Nikon trend is very clearly towards more and more obscuring of critical data, and at some point they cross a line and need to be called on it. The D2x crossed that line.
