Overview

The Heliopan B+W 1029 Dark Red Filter serves as an intense monochrome separator engineered to create extreme, punchy contrast in analog and digital film setups. By mercilessly absorbing blue and green light wavelengths, this optical tool drastically accentuates the red spectrum to produce ink-black skies and explosive, high-drama cloudscapes. Beyond fine-art landscaping and infrared photography, its unique spectral profile makes it excellent for studio document restoration—pulling text off yellowed archival pages—and generating eerie, day-for-night moonlight simulations. This glass is paired with an external 4-layer multi-coating that minimizes reflection-induced glare while acting as a dust-shedding barrier for cleaner field execution.

Features

• Extreme Monochrome Contrast: Shuts down blue and green tones entirely to force deep, black sky rendering and intense architectural outlines.
• Document & Tone Separation: Isolates specific color channels to rescue fading text on aged papers and balance tonal values in forensic imaging.
• Four-Layer Anti-Reflection Coating: Multi-coated exterior shields the glass from contrasting-killing ghosting while forming a slick, water-resistant surface.
• Flawless Schott Optics: Employs ground and polished Schott glass to retain pristine center-to-edge resolution and maintain neutral exposure damping.
• Low-Profile Brass Frame: A compact 4mm rim protects against edge vignetting on ultra-wide 24mm full-frame or 18mm cropped lens assemblies.
• Smooth Glide Threading: Crafted from heavy-duty brass that resists extreme weather expansion, ensuring the filter never binds or jams to your lens.
