This property gives information on the angles component of orientation of the Photograph's Camera Station (i.e. the angles of the camera station at the time the photo was taken).
When this property is expanded (i.e. by clicking the small + next to the property title), The Omega (deg.) is the rotation about the X axis, the Phi (deg.) is the rotation about the Y axis, and the Kappa (deg.) is the rotation about the Z axis. Also see Orientation.
Note: the values for orientation of the Camera Station can be changed here - you should be quite confident in your coordinate systems before you do this. When any of these values are changed, the Camera Station will be set to be "oriented". In other words, this is a method of manually orienting a Camera Station. This might be useful when you know the photo positions before hand (such as a stereo camera setup on an ROV).
