Practical filter guides and field notes from XT Filters founder Leo Liang — written for working photographers choosing CPL, Black Mist and protection filters in the field.
Start with the News journal, read our Black Mist guide, or jump to the filter size guide when you need a thread-size check before checkout. For shipping, returns and warranty, see the FAQ and policies.
Our editorial approach centers on side-by-side optical comparisons, real-world flare testing across mirrorless lens systems, and straightforward setup recommendations. We publish actionable shooting techniques rather than generic spec sheets, helping photographers choose the exact filtration density, coating type, and thread size their creative vision demands.
