If it is a tripwire shot, then how can the photographer own the copyright if the composition included material that wasn't there when the photographer framed it?
This goes back to an another post where an instructor tells everyone how to frame a subject in order to take a photograph. In that instance you would be arguing that the instructor owns the copyright because the instructor decided what the composition was which is clearly incorrect.
If a random stroke of lightning automatically sets off the camera to take a picture that happens to include lightning that wasn't there when the image was framed then how can the photographer claim that it was their composition of the lightning that created the image?
This has been addressed elsewhere in the thread, please re-read it.
Yes and you're wrong.
