I was strolling through a park at night and saw a man lighting up a cigarette. It lit up his face which was still spotted with shadows. I found the effect particularly cool and it immediately reminded me of Vimes. If my memory serves me right, it happens in a couple of scenes in Night Watch and Thud? It took me a bit by surprise that I don't recall ever seeing this effect in person before and how I associate the imagery with Vimes. Just wanted to share this with others who might understand.
