The Mist diffusion fog filter is used to create softening images.
The filter scatters strong light without affecting the sharpness and contrast of the image. It is mainly used in portrait work. Small skin defects can be almost completely eliminated, wrinkles can be softened.
Despite the fact that the main purpose of diffusion filters is portrait photography, they also work well when shooting landscapes in good Sunny side, and especially contour lighting. Their effect can be compared to the “soft focus”effect. Using these filters, sharp borders are softened in the landscape.
