Cabin Crew would not let me take photos during take off !

On my recent trip Liverpool-London City-Liverpool, I was all ready to get some great shots…..until the rather rude female cabin crew on the LIVERPOOL-LONDON leg said i was not to take photo’s during take off as it’s a health and saftey matter and my attention should be on the plane during takeoff !, What about the 4 business guys laughiung at a newspaper report a few rows ahead, thats just as bad I said, but she wouldn’t have it 😡

I couldn’t even get away with it as I was in seat 13D (the very rear row, right next to their seats!!!)

Anyway on the return I managed to snap a few….does anybody know what the rainbow effect is on the third image?
