I'm not certain this has been thought through sufficiently. If an organization is in a position to confiscate the camera from a journalist, they're almost certainly ALSO in a position to extract the encryption password from the journalist.
It would be far better if the cameras automatically uploaded these photos[0], and could be configured to upload them somewhere outside of hostile reach, such as servers owned by the magazine/paper they work for.
A side issue is that being able to prove authenticity would be valuable, as the issue of faked news/images becomes more visible in the eyes of the general public. Having some sort of GPG signing of (image + gps time + gps position) would be valuable, although establishing the trust chain in practice would be quite difficult and requires some serious thought.
0: Yes, there's a question of how you get internet access in places such as the middle of a warzone, but something generic like wifi would allow individual papers to provide something like a satellite wifi bridge to enable uploads regardless of location (although the cost would obviously be large).
