There’s an almost out-of-control breathlessness at this point of the wedding day as bride and groom feel as though they are being rushed towards their destination (there’s no getting out of things now!). I don’t think you need to see the faces to sense the nervousness of this pre-ceremony moment. “Is my dress OK?”, “Can anyone remember which order we’re supposed to go up the stairs in?”. That sort of thing.
I always try to get an overhead view at some stage of the wedding. It breaks up the flow and introduces a bit of variety into the wedding album.
