\" I just wanted to make a brief comment about your analogy between the human visual system and cameras. I think one of the reasons that some people enjoy photography so much is that our visual systems are different from cameras in a number of important ways. New information is sent from the retina in volleys to visual cortex at a rate of approx 3 Hz (new volley every ~300 ms.) Old information which was not encoded in memory is continuously lost. Further, a great deal of information which does get encoded may prove very difficult to retrieve, or may be retrieved inaccurately, or incompletely. I think these features of human cognition actually play a crucial role in our capacity for higher order reasoning, imagination, and creativity all the good things about being human. But I think photographs are so enjoyable because they are static, and they allow you to see visual as well as conceputal relations which are likely to otherwise go unnoticed in the hectic stream of information that bombards us as we navigate the environment.\"
