The Heliopan 40.5mm Cross Screen 6x Filter is a star effect filter providing 6 reflected light points stemming from specular highlights within the image frame. When the filter is rotated in front of the lens, the points shift in direction but always retain their symmetry. This effect is caused by thinly etched lines on one of the planes of the filter and is most prevalent when highlights are photographed against a dark background, such as a streetlight on a dark street.
