This is an great introduction to a key photographic theme: how to develop the ability to see. As Henri Cartier-Bresson wrote, "Technique is important only insofar as you must master it in order to communicate what you see. . . . In any case, people think far too much about techniques and not enough about seeing."
Michael Wood and I take this discussion further in our book "The Practice of Contemplative Photography: Seeing the World with Fresh Eyes." You can learn about this approach at the book's website seeingfresh.com.
latyshevv: Neurological premise of this article is outdated and is simply false.
If you understand the "neurological" terms as metaphors for two ways of knowing, or thinking, then this holds up quite well.
