soft-focus

Soft-focus is a cinematographic effect in which a filter, vaseline, or gauze-like substance placed over the camera lens reduces the clarity or sharpness of focus, blurs the image, and produces a diffused, hazy light. The visual effect of soft focus can also be created by simply shooting out-of-focus. It is often used to enhance romantic or dreamy scenes or to remove wrinkle lines from an actor's face.
