Recommended for portrait work, as small skin blemishes and defects become less visible.
Facial contrast and wrinkles are also softened.
As these filters are principally used for portrait work, the lens aperture should be opened (lowest f-stop) to diminish the depth of field so that the subject stands out well against the background.
