This photo has three light zones.
The brightest part is on the left hand side, showing hills yonder with their shadows.
The middle zone showing the somewhat reddish rock with their many joints as a result of weathering.
It also shows the silhouette of my brother and sister in law walking under the overhanging rock.
The picture was taken by my wife while travelling in the South Western part of the States.
Altogether, it makes an interesting picture!
