Filters that soften, lower contrast, and create mood.
DIFFUSION FILTERS
Diffusion filters are used to soften the image without making the subject look out-of-focus. They are manufactured from a wide range of textured-type patterns, including nets, concentric circles, tiny lenslets, subtle ripples, minuscule particles, frost-like glaze, and various computer-generated configurations.
Each type is usually supplied in sets of 3 to 5 strengths. Depending on the type used, along with the lighting conditions, each produces its own unique effect.
Some flatter the subject by smoothing-out wrinkles and toning-down blemishes, some lower contrast and pleasantly mute colors, and some flare highlights while adding a mood to a scene.
. . .There are at least two dozen popular types, all of which are attainable through the Filter Gallery.
