Soft focus filter for Cokin P series
Diffusion filters are used to create softer images. Basically, a
diffusion filter diffuses light without affecting the sharpness and
contrast of the image. Thus, it is different from the effect of
being out of focus.
They are mainly used in portrait work but can also be used to
soften a landscape. In portraiture, small skin defects can be
eliminated almost completely, and facial contrast and wrinkles are
softened.
