Cokin star filters will create as many stars as there are light sources in your picture.
You can achieve sparkle from city lights, birthday candles, stage projectors, or reflections off water, metal or glass.
Star filters are most effective against dark backgrounds.
Their effect can be reinforced by combining with color, graduated or sunset filters.
Available in 2, 4, 8 & 16 point stars as well as a 'softstar' effect
