I have been asked by a few photographers how this was shot so here goes, pretty simple really, Camera used was a Canon 1D MKIV with a 70-200 L IS lens shooting at f5.6 at around 150mm of the 200mm end, there is a off camera flash (580 MKI) to the right controlled by a pocketwizard transmitter firing across to the left of the couple, just enough to cast a small amount of light falling on them but not directly at them, hence why the bush to the left of the couple is lit slightly.
Oh I just noticed that big red sign in the background of the video :)
