Using natural light and shadows around us

In each Picture Max Dupain uses the natural light for effect. He uses the sun and where it is in the sky to create depth and to make the viewers eyes get drawn to a certain point in the image. For example in image 1, Max Dupain uses a peer and takes a picture of a woman pushing a wheel barrow and also 2 little kids playing with the little girl pointing to the left. Max uses the light of the sun to have the effect of the railings to create a shadow that is perfectly straight running all the way to the little house/shed at the end.
