Star Filter A star filter is a specialized photographic filter that creates a starburst effect around bright points of light in an image. It consists of a transparent filter with a pattern of etched lines or grids that diffract light rays, causing them to spread out and form star-shaped patterns around light sources. Star filters are commonly used in night photography, landscape photography, and portrait photography to add visual interest and artistic flair to images. They can enhance the appearance of streetlights, cityscapes, Christmas lights, and other illuminated subjects by creating sparkling starbursts that draw attention and create a magical atmosphere. |
