The beauty of Fan Ho's is due to its simplicity: two perfect triangles, one dark, the other light, and a slim rectangle on the left hand. The woman seems so little and calm. The composition is perfect, as it is the image.
I took the other picture at the Brandhorst Museum in München. The texture of the building is more complex due to the ceramic facade, which tourists love to photograph, and the windows. Here, the shadow is much smaller, so that the second triangle is missing. Still, the guy is standing in the same spot, but showing an active attitude towards the building.
