The horizon line is the distant line where the earth's surface and the sky appear to meet. It represents the viewer's eye level and can change based on the observer's height and perspective. In art and photography, the horizon line is crucial for creating depth and perspective in a composition.
In landscape paintings or photographs, the horizon line helps to establish the scale and orientation of the scene. It can also influence the mood of the artwork, as a high horizon line may suggest vastness, while a low horizon line can emphasize the foreground. Understanding the horizon line is essential for artists and photographers alike.
