Photos in flight? Bad idea!
Have a look at NTSB accident report number CEN14FA265. Selfies in flight, inexperienced pilot flying in conditions for which he had no qualifications.
Combine these two ingredients, and its amazing there are not more accidents.
Leave the cameras behind, that's what I recommend to those flying for the first time. Let your girlfriend take the photo when your aircraft is on final approach, so it won't be your final approach!
