Henri Cartier-Bresson

Henri Cartier-Bresson was a french photographer and was considered the father of photojournalism.  He sees the camera as a sketch book and said "In order to “give a meaning” to the world, one has to feel involved in what one frames through the viewfinder."  

To capture photos like the one above he uses concentration, discipline of mind, sensitivity, and a sense of geometry.

The photo above shows geometry through the repetition of the fence and the ladder. how the reflection shows a totally different person because the foot is not touching the ground.  Bresson showed contrast, use of line and reflection really well in this picture.
