This ! I noticed too - excitedly, really looking and turning to him waiting for him to do the same for the shot !Irrational annoyance but something I’ve spotted in all the wedding videos. When they are walking together she turns her head several times to face and intensely grin at Jack (who is oblivious lol) and I just KNOW it’s cause she’s hyper-aware of getting ‘the perfect action shot’ of her smiling lovingly at him. She can never just be in the moment, always thinking of ‘the content’.
