Making a hand motion squiggle graph
Question: What do you get when you shoot a hand-held photograph of Venus through a gap in the trees at ISO 3200 with a slow medium telephoto zoom and heavily crop the result? Answer: An image that says more about the motion of your hand than the object of inquiry, one that projects a sharp white line plotting the motion of your hand over 1.1 seconds onto a murky, blurry representation of the sky and trees. You begin by looking at nature and the heavens, but the result is more an exploration of inner space than external reality. Call it observer's bias. As in so many things.
