fényváltozás

Fényváltozás is a Hungarian term that translates to "light change" or "change of light." It can refer to several phenomena, primarily within the context of optics and art.

In optics, fényváltozás describes the alteration in the intensity, color, or direction of light. This can occur due to a variety of factors such as scattering, absorption, reflection, or refraction of light by different media. For instance, passing sunlight through a prism causes a fényváltozás, splitting white light into its constituent colors. Similarly, the way light interacts with surfaces, creating shadows and highlights, is a form of fényváltozás.

Within the realm of art, particularly painting, fényváltozás refers to the artist's deliberate manipulation of light and shadow to create form, depth, and mood. Techniques like chiaroscuro are prime examples of employing fényváltozás to achieve dramatic visual effects. Artists use variations in light and dark tones to model figures, suggest volume, and guide the viewer's eye. The overall atmosphere of a painting is often heavily influenced by the artist's handling of fényváltozás. In essence, it's about how light is depicted and how its changes contribute to the visual experience.
