About DiffusionFilter.com
Diffusion filters take a strong light source and spread out or scatter it without affecting the sharpness and contrast of the resulting image. This helps to avoid having the light source originate from a single concentrated source. This is sometimes called the Spotlight effect and results in blown-out highlights and extremely harsh shadows. Even stronger diffusion filters can be used to create a hazy or dream-like affect often used in creative photography scenes.
