Cokin Gradual Blue 1 Filter X-Pro Series -
• Blue Graduated filters enhance the sky while they underline the colors of mountain landscapes.
• They are also the filters for sea photography where they intensify the white sparkle of breaking waves. They are available in five variations.
- XP123L - 2X Light starts with the same neutral density as XP122, but feathers the blue almost from the color edge and more gently graduates to clear. One stop of compensation.
- XP123 - B2 graduated blue filter reduces the light 3 stops.
