..really.Nothing. No extreme weather. No anecdotes of random encounters with strangers on Westminster Bridge (believe me, I've met some interesting people on that bridge at 6 o'clock in the morning, but that's a blog for another day!).
Everything just worked. The light was just right. The headlights helped balance the composition , and as if on cue the jogger appeared in the frame, and all the elements just slotted into place.
That's it really. Hecho! Nada más !
