Overview

The Heliopan B/W 1015 Yellow Dark Filter is a premium optical contrast filter specifically engineered for monochrome film photography. By heavily dampening blue wavelengths, this filter provides strong cloud separation and a heightened depth effect, making it indispensable for landscape photography under high midday sun and harsh shadows. Each filter features a 4-fold anti-reflective coating that boosts contrast, minimizes light loss, and forms a water- and dirt-repellent barrier that keeps the optics pristine during outdoor assignments.

Features

• Heavy Blue Suppression: Drastically darkens blue tones to produce striking cloud definition and enhanced atmospheric depth.
• Advanced 4-Fold Coating: Precision multi-coating minimizes reflections at air-to-glass surfaces while repelling water, dust, and fingerprints.
• Schott Glass Substrate: Crafted using fully ground and smoothly polished Schott glass for exceptional sharpness and neutral tonal rendition.
• Slim Vignetting-Free Frame: A compact 4mm profile prevents edge shading on full-frame lenses down to 24mm and APS-C setups down to 18mm.
• Durable Brass Cell: Precision-machined brass ring resists temperature-induced warping and prevents binding or cross-threading in the lens mount.
• Double-Threaded Utility: Features an identical front thread matching the screw-in diameter to accept secondary filters or matching lens hoods.
