This is a great quote from Henri Cartier-Bresson regarding the importance of composition in creation of great photographs.
This recognition, in real life, of a rhythm of surfaces, lines, and values is for me the essence of photography; composition should be a constant of preoccupation, being a simultaneous coalition – an organic coordination of visual elements – Henri Cartier-Bresson
He is one of the most prominent photographers who understands the idea of the moment. His photography captures a moment in time with real people in real life. He is a street photographer if there ever was one. You can learn more about him here.
