With a few twists the camera focuses its lens, and the image becomes crystal clear. How easy it is for this machine. How simple the dynamic. When it loses focus it is just as mechanical - an accidental movement in its case, no intention. When we lose focus it is never accidental. We choose to lose it for a reason. It is excruciatingly terrifying walking about when things are blurry - but there is also release in the unknown. It is exquisite when all there are are soft edges and swimming colours. It is art.
