Professional Filter for Cinematography

The Schneider Optics Digicon #1 is a 4x4 inch camera filter designed for professional cinematographers who need controlled highlight and shadow detail. It raises black levels while lowering highlights so that a higher dynamic range can be recorded when combined with in-camera gamma settings or post production. The filter produces no colour shift and keeps highlights clean and halo-free.

Optical Consistency and Durability

Each filter is diamond cut from crystal-clear water-white optical glass and ground to precise flatness and plane-parallelism verified by laser interferometer. A densitometer checks consistent density and a spectrophotometer confirms proper light transmission. This ultra-high consistency allows cinematographers to swap like filters mid-shoot with no discernible variation in colour or effect.

Reliable Build for Demanding Sets

Schneider filters are built to stand up to the most rigorous demands on set or location with a specially formulated construction that ensures longevity. The professional grade materials and manufacturing process virtually eliminate the need for lab colour timing correction. Buyers who need filter sizes other than 4x4 inches or who require different density grades should look elsewhere.

Questions about this item

How do I install the Schneider Digicon #1 4x4 filter in a matte box without scratching the optical glass?

Handle the filter by its edges only, align it with the matte box tray guides, and slide it straight in until the retaining clips engage; the diamond-cut water-white glass is ground to precise flatness and plane-parallelism, so any tilt during insertion can bind or chip the coating.

What cleaning routine preserves the Digicon #1 filter's halo-free highlight performance over time?

Use a rocket blower first, then a single drop of isopropyl alcohol on a lint-free microfibre cloth wiped in a spiral from centre to edge; the spectrophotometer-verified transmission and densitometer-checked density mean any residue or micro-scratch will alter the consistent contrast curve.

At what point does heat from continuous high-power lighting degrade the Digicon #1 filter's contrast effect?

The crystal-clear water-white optical glass is tested for stable transmission, but sustained infrared load from large HMI or LED arrays can gradually shift the filter's black-level lift; monitor shadow detail on a waveform and rotate in a spare filter if highlight roll-off drifts.
