While watching an image, (443) Photographica has the ability to cause a discontinuous change in the global perception, by bifurcating attention on to small details that are part of an ordered and recognizable structure, alternative to previous global perception. The most famous dual image of this type is the one of a young woman - old woman depending on how you look at it.
