I would like to talk about a photograph I saw and commented on at a photography site I visit when I have time. I found it very interesting both as a photograph and as an example of how we perceive the image content, I asked for permission to use the image from its owner, Jarno Saren, who graciously allowed me to use his photograph as the subject of one of my blog entries. So, here we are and I want to start first by showing you a part of the photograph to set the stage. Take a look at the photograph below and think about the stairs. How would you describe the directionality of the stairs?
