Chiaroscuro is a term used for a work of art with high contrast between light and dark that affects the whole composition. Another term that could be used is low-key. This low-key effect accentuates the contours of an object by throwing areas into sharp contrast between light and shadow.
The composition presented hear is one of the strongest low-key images I have seen is sometime. The blacks and whites take over this photograph with very little mid tone gray. It has a film noir quality. The structures with their different heights from left to right lead the eye up into the sky with its gray to black tones in gradations.
When digitized images with high contrast are transmitted or sometimes when they are printed they have a tenancy to block up in some areas where there are a lot of pixels of the same tone. This has happened to the photograph as shown here.

Shot in North Liberty, Iowa in the back roads traveling in Eastern Iowa, thi black and white graphic image was best
shot on a clear day, with a Tokina 2.8 28-70MM lens,
mounted on a D300 Camera. The image effect resulted
from transposing a gradient dark grey-black background
substituting it for the blue sky,and then trimming up
the subject matter with the highest contrast I could
to pop it, for the human eye. Hope you like it!
