Some of the photos that I love the most are the ones distorted by light or atmosphere. They can capture the ephemeral moments of abstraction that we generally try to avoid in going about our everyday business because they are ambiguous and challenging.
Perception is dependent on mood, circumstance, need, and attention. It is more selective than most people imagine as we are brought up to believe in a solid world of absolute structure- but most of this is an illusion. There is always way too much going on for our receptors to cope, so we unknowingly adapt our perception to block out most of the stimuli that compete for our attention.

I was never any good at physics- much too busy in the art room- but I just love science and it really worries me that people who want to tell us that life is a collection of simple problems with easy solutions are threatening to undo centuries of civil trust in scientific methods and institutions, and that it will be at the expense of us all.
