Our Stellar Filter Kit lets you create starburst effects from bright and close light sources so they appear as 4-point, 6-point or 8-point stars. For best results, use with a strong, close and partially obscured light source like the sun peeking through the tree canopy. Our Star Filters don’t affect exposure and bring a subtle elevation to your photography. Please note the shape of your camera’s aperture affects the shape of the stars. The starburst effect is stronger with a polygonal aperture and weaker with a round aperture.
