Can't Get Away From Math

From about 6th grade all the way through college, any kind of math was a real struggle for me. And the problem with math is, you can never really get away from it. No, not every job requires the daily use of calculus or geometry, but math in some form is still a part of almost everything we do. Even art involves addition or subtraction.

For the person who paints or draws, art is about addition. The artist starts with a blank canvas or piece of paper, and then adds whatever elements are needed for the composition. For example, if the artist wants to paint a landscape, he might add a tree, a cloud, some mountains, or whatever else he wants to appear in his painting.

Photography, on the other hand, is about subtraction. The photographer starts with everything that is in the viewfinder, and by various methods, subtracts what is not wanted in the composition. That beer can in the foreground of my landscape? I have to physically remove it, or change my camera position or zoom my lens slightly so it doesn't show. If I am really lazy, I can remove it later with software. Since the camera gives equal emphasis to everything in the viewfinder, the photographer has to decide what doesn't belong, or what distracts from the main subject, and subtract it. The failure to subtract non-essential or distracting elements from a composition is often what separates good photos from mediocre work.

On the photo above, I wanted to isolate a single red leaf that was on a bush that still had hundreds of leaves, many still green. I did this by zooming in close to eliminate the other leaves, and then going with a square crop on the computer to further eliminate any other distracting elements. I titled it "One Left" because it looks like the last leaf left on a branch, when actually it's one of several left. The painter or photographer can create their own reality. A painter would have added only one leaf to his painting for this objective; as a photographer, I had to subtract everything else to get the composition I wanted. Math, you just can't seem to get away from it!

  1. John, this is one of your best thought provoking posts in a very long time.
    I really like the addition and subtraction theme.
    Math has always been my nemisis , but you are right.
    There is no way of living life without it.
    Love the One Left.
