Light diffusion is the process by which light spreads out as it passes through a material or reflects off a surface. This phenomenon occurs when light encounters particles or irregularities in a medium, causing it to scatter in different directions. Common examples of diffusing materials include frosted glass and certain types of fabrics. In practical applications, light diffusion is used to create softer lighting effects in photography and interior design. By using diffusers, such as softboxes or light panels, harsh shadows can be minimized, resulting in a more even and pleasing illumination in various settings.
