Before departure in my old GA days,often the pax would hand me their cameras so as I could photograph the group in front of the aircraft.
Trouble was all these fancy cameras had all the doo daads,but I always had to ask them to set them up & tell me which button to push.
Pax:'' Aye,guys....he can drive an aeroplane but he can't drive a camera''
Me: ''Well,we don't do a course in camera ops when getting a pilot's licence''
