Landscape images are often showcases for horizontal lines in an image.
The horizontal lines of the image of Lake Cargelligo and reflections is made up of horizontal lines each mirroring the other. The further foreshore has a line of trees and the cliffs separating the sky and the lake water and the reeds form a horizontal line of foreground interest.
This pretty picture of salmon encrusted with fresh fruit and vegetables forms a horizontal line across the plate. The hollandaise sauce shadows the line of the coloured salmon. A simple but elegant dish.
The image of the Hubbard Glacier in Alaska is constructed with horizontal lines. The glacier fills the middle foreground, the ocean in front follows the line of the glacier and the darker cloud formation in the sky again shadows the horizontal line of the glacier.
