ONLY A SMALL PERCENTAGE OF OUR MIND’S INNER LIBRARY OF ACCUMULATED DATA is at the top of our consciousness. Staying aware of everything we’ve learned in our lives, every minute of the day, would obviously lead to a mental train wreck, as the vital and the trivial created an endless series of collisions between what we need to know and what we need to know right now. The brain, acting as a wonderful prioritizing network, moves information to the foreground or tucks it toward the back, as needed.
The visual patterns we’ve developed over a lifetime are also at work in how we create and interpret photographs. We know in an instant when we’ve seen something before, and so we process known objects in a kind of short-hand rather than as something we’re viewing for the first time. This allows us to make camera images that are abbreviated versions of things we first encountered long ago, images that merely suggest things, rather than delineate them in full detail. Call it abstraction, call it minimalism, heck, call it a ham sandwich if that helps. It merely means that we can use our brain vaults to show parts of things, and count on our memories to recognize those things solely from the parts.
Focus is but one such way of supplying visual information to the brain, and its selective use allows the photographer to convey the idea of an object without “spelling it out”, or showing it in absolutely documentarian terms. In the image above, our collective memory of the contours and details of a dollar bill are so deeply ingrained that we don’t actually need to see all of its numbers, letters, and images in full definition. Focus thus becomes an accent, a way of highlighting some features of a subject while downplaying others.
It may be that, in photographing selective aspects of objects rather than showing their every detail, we are teaching the camera to act like the flashing fragments of memory that our mind uses to transmit information….that is, teaching a machine to see in the code that we instinctively recognize. Is all interpretation just an attempt to ape the brain’s native visual language? Who knows? All that we really have to judge an image by is the final result, and its impact upon other viewers like ourselves.
