F stop controls the amount of light coming in through the lens.
Taking a digital photography class with
Rick Wright, I am learning about composition, light, pattern and texture...all the things you can do with a digital camera. But, I'm not thinking about F stops, or the more technical end of photography. For this, I am grateful. Each thing in due course.
But F stops are important. And F stop is a number that represents the size of the aperture. The aperture controls the amount of light coming in, which can affect many photographic elements. The smaller your F stop number, the more light comes into the picture, decreasing the depth of field. The smaller the aperture opening, the greater the depth of field.
I wrote about this in an earlier essay, and I find I still have trouble with it. Yes, I struggle with keeping an eye to the close and far away, keeping a sense of three-dimensionality, both in my photographs, and in my perspective.
I tend to make pictures that use symbols, abstractions, a language of shapes and images. I am interested in a narrative coming across. But a good writer keeps an eye to the bigger picture, the distance, while articulating the close-up details. How can we do this in our lives?
Well, the first thing is to admit that you can't actually focus on both. You can focus most of your attention on one and hold the other in the periphery, as a balance, as a context. This requires a little bit of doubled vision. It requires discipline. And it requires a clarity of purpose, so that the doubled vision doesn't contain too much, doesn't become a chaotic or messy vision.
I am writing a novel. There are moments of grand vistas, and moment of the smallest shift in an eye. How to hold that tension between the two? The only way I know is focus your vision into a small frame of light, narrow your vision, squint your eyes.
