Diffuusivalo, often translated as diffuse light, refers to light that has been scattered in many different directions. Instead of originating from a single point source like a direct sunbeam, diffuse light comes from a broad area. This scattering can occur through reflection off irregular surfaces, transmission through translucent materials like frosted glass or clouds, or through the phenomenon of Rayleigh scattering in the atmosphere.

The primary characteristic of diffuse light is its lack of harsh shadows. Because the light arrives from multiple angles, objects illuminated by diffuse light appear soft-edged and evenly lit. This is in contrast to direct light, which creates sharp, well-defined shadows. Diffuse lighting is often found on overcast days when sunlight is scattered by clouds, or indoors when light bounces off walls and ceilings.

In photography and art, diffuse light is valued for its ability to create flattering portraits and smooth textures. It reduces contrast and minimizes distracting highlights and deep shadows. Natural phenomena like the soft light of twilight or the illumination within a dense forest canopy are also examples of diffuse light. Understanding the properties of diffuse light is important in fields ranging from lighting design and optics to meteorology and visual perception.
