Linear Rainbow Filter - This rainbow filter creates a cinematic streak of rainbow flare in one axis that can be adjusted by rotating the filter in front of your lens. The smaller and brighter the sources of light, the stronger the effect.

Starburst Rainbow Filter -This rainbow filter produces a four-axis burst of rainbow streaks. The sharper the points of light, the stronger the effect.

Swirl Rainbow Filter -This rainbow filter creates a seashell- the spiral-shaped rainbow pattern when point sources of light are present in your image. Brings a soft glow with subtle rainbow effects to your images when shooting images without bright point light sources in the frame.
