SOFTER AND QUIETER
By MICHAEL PERKINS
THE MEANING OF THE WORD NOISE HAS, IN RECENT YEARS, been expanded beyond its familiar role as an audio term, extending its usage into our visual vocabulary as well. A key shift in photo terminology, as film converted to digital, has been the re-purposing of the word to denote a degradation in quality, with noise replacing grain as the way to describe a less-than-pristine image. Same idea, different wording.
And now, in recent years, I have heard the word used even more widely to denote weaknesses in a composition, describing a picture with too much information or distraction as “noisy”. In a recent post on the blog PhotographyMad.com, you find the following citation:
Often a photo will lack impact because the main subject is so small it becomes lost among the clutter of its surroundings. By cropping tight around the subject you eliminate the background “noise”, ensuring the subject gets the viewer’s undivided attention.
I personally would extend this metaphor to include not only the subject matter within a frame but its color range as well. That means, simply, that too many colors in an image might dilute the effect of a shot as much as the density of its elements, and extends the idea of noise to encompass anything that lessens the communicative power it has for the viewer.
In the above shot, the idea of the composition was to convey the bits of orange peel as some kind of spent or withered flower. I didn’t decide, in advance, to eat an orange in a yellow bowl, but I believe that the same peels in a red bowl might have hardened the look of the shot by calling attention to contrast instead of content. Keeping the entire composition to a two-tone color range (along with a decidedly shallow depth-of-field to reduce the texture detail) rendered it nice and soft. Of course there are a million ways to conceive this image; I just chose this way.
Noise is not merely a technical registration of visual or audio distortion. I think the word has real value if you’re looking to streamline your images. Just think noise=clutter.
Then turn down the volume.
