Chiaroscuro - A monochrome picture made by using several different shades of the same color.
A black-n-white photo or what?
No, not exactly.
The term was originally aimed at paintings.
The word has its origin from Italian. “Chiaro” means light, “scuro” dark. Chiaroscuro – lightdark.
It is a painting working with contrasts, rather than with colors.
A black-n-white photo can be considered as chiaroscuro if the contrasts are part of the composition, like a streetlight leaving part of the sidewalk in darkness.
So among the words I found an art term.
Well, perhaps not a word I will have great use of, but I can always take a walk along the paintings at an art museum and burst our “chiaroscuro” now and then.
Or perhaps join a group studying a painting and say “his chiaroscuro technique is really fabulous”.
