I was making some portraits in a house in Islington yesterday and took pleasure in admiring the owner's collection of prints of iconic images from some of the world's greatest photographers, including one signed by Henri Cartier-Bresson of his shot of a man jumping through a puddle behind Saint-Lazare station in Paris, often cited as the best example of the 'decisive moment', a term coined by Cartier-Bresson himself.  I remember thinking of that famous image as I released the shutter for this one, and wondering whether or not it would have been better if the floor had been shiny.
