The Heliopan Cross Screen 8x Filter is a star effect filter providing 8 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. Stronger and smaller highlights produce the most dramatic effects. Longer focal length lenses are the most effective. Should not be used at small apertures. Cross star lenses will also slightly diffuse the scene.
- Constructed from Schott glass for optical clarity.
- Brass filter ring helps to prevent jamming and provides additional strength.
