What these images have in common is the idea that precedes the first shot, and the realisation that sometimes only requires two exposures, sometimes 102.

The reason? It can be prosaic (children never look where we want them to, as in the case of the Big Service picture), sometimes it's necessary (who has the patience to wait until so many yellow cars are on the bridge? See: 33 and a half taxis), sometimes the idea is too futuristic (The grinder sings for a good lunch). Not to mention the lighting of the Parliament, which at the time the picture was taken was futurism incarnate...
