What is focus?
The Free Dictionary says:
1. A point at which rays of light or other radiation converge or from which they appear to diverge, as after refraction or reflection in an optical system
2. A center of interest or activity.
Is it clear enough? It’s a definition, and so it puts the point on comprehention. And definitions always work. Our intellect search always for comprehensive, clear, well-focused definitions and meanings. We always search for centers, converging lines a.s.o. We do not understand explanations or other things that don’t meet this requirement. And we flee from the “dark” side. But isn’ dark side part of our being?
Every definition of the term above correlates with a point. But the point truly exists? What if, just as numbers, is a pure fiction without any consistency? And this pure fictious element defines Photography entirely? What if a line (mathematical abstraction, too) is used instead of a point to define this art major constituent? Or why not: a mathematical plane. Or the whole space? Or lines coud converge only to a single point to be understood, unless its pointless? Strange ethimology: pointless.
In other hand: focus does not eliminate converging lines. They exist without the final point. But the lines are still in move, approaching their goal. They are on their way to reach something. They just did not find yet their meeting point. And so it’s not finished: And because it’s not finished it’s pointless. Strange syllogism, too.
Is focus elementary to photography? Why don’t we suspend this single point? Why don’t we better define a plenty of points, moving or staying of their own wills or own rules, and let’s free our lines? I think we should not constrain everything toward focus. We have a peripherical seeing, too, that is not in focus, but we still use it. So, out of focus it has no point? We don’t see it, it does not exist?
Does not have a sharp focus? Maybe you are not there, yet. But keep moving, ride the lines, and you will arrive somewhere you should never imagine.
