Pros & Cons

👍 Pros

  • Available in a B1 graduated blue filter version, specifically reducing light by 1 stop for nuanced sky enhancement.
  • Offers a B2 graduated blue filter variant, providing a stronger 3-stop light reduction for more dramatic effects.
  • Includes an XP123L variant with a gentle light blue graduation, ideal for subtle sky enhancement with 1 stop compensation.

👎 Cons

  • Requires a compatible Cokin X-Pro filter holder system, which is not included with the filter itself.
  • The "XL" designation implies it's a larger filter size, potentially making it bulkier to carry and requiring larger lens adapters.

  • As a graduated filter, its primary use is for landscape photography, making it less versatile for other photography genres.
  • The specific impact on color temperature beyond "blue" isn't detailed, which could be a consideration for accurate color rendition.
