This is the ultimate stair photo. I read that Mr Evans spent hours in this cathedral, just watching how the incoming sunlight changed the shadows in the building. Evans had photographed this stair already a few times before coming to this result. Because of the use of telelens, there is not much depth in the image, making you feel as if the stairs are coming towards you like a wave and giving a flowing sense of movement. (Photography - The whole story, pg 201)
This picture is a great example of how lines and shapes bring movement and direction in an image. I have taken a few stairs photos myself and find it very difficult, up till now actually impossible to bring this sense of life in an otherwise solid object. It does take a lot of time and observation to get it just right. I need to practice being patient and become more persistent in getting the most out of objects, places and people in my images.
