I think what you got here is actually "ghosting". For the purpose of this discussion, let us call your friend Panduram. So, Panduram was leaning back in his chair slightly when you started taking the photo but was not leaning by the time the camera finished. All this time the camera's sensors were taking in the light from the scene; Panduram was leaning for a very short while as compared to the time he was not. That's why you have a faint image of position 1 (leaning) superimposed on the stronger position 2 (not leaning) image.Go Panduram!Perhaps you guys should try this again 🙂Brian.
