Like most cameras nowadays, the Nikon 1 series have an orientation sensor and record the camera orientation in the image data and use this in review/playback.
I took a photo looking vertically down on a flat object on a table. I had composed the shot in landscape orientation (Nikon call this "wide") but in review/playback mode the camera displays the image in portrait orientation (Nikon call this "tall").
I've searched the reference guide but can't find a way of changing the orientation of a specific image (you can turn off the recording of orientation for future images).
Have I missed something?
Update: I wanted to do this in-camera. (I'm familiar with computer tools like Picasa, Ifranview and ViewNX).
