DoPchoice introduced a practical solution designed to eliminate light leaks from butterfly and frost frames, the Spill Killer. This accessory ensures cinematographers and gaffers can maintain precise light control without unwanted spill or distracting shadows around diffusion setups. By sealing gaps between scrims, grids, or flags, the Spill Killer provides a clean, professional lighting environment with minimal setup time.
Founded in 2008 by cinematographer Stefan Karle, DoPchoice specializes in creating innovative light-shaping tools tailored for professional film crews. Headquartered in Munich, Germany, the company focuses on developing compact, lightweight, and user-friendly solutions that streamline lighting setups both on location and in studios. Their product lineup includes softboxes, grids, and now the Spill Killer, designed to give filmmakers more control over their lighting environments.

We recently covered the DoPchoice AIRGLOW FLOAT, an inflatable round toplight modifier that adds flexibility to on-set lighting setups (read more here). Now, the company is back with another innovative tool to improve lighting control.

Addressing light spill challenges
Light spill is a common issue on set, especially when working with large diffusion frames. Butterfly and frost frames often allow stray light to leak from the edges, creating unwanted shadows and reducing control over the lighting setup. Traditional solutions, such as using flags or makeshift fabric ties, can be cumbersome, time-consuming, and often fail to provide a seamless seal. The Spill Killer offers a fast, effective, and professional solution to this problem.

Spill Killer – overview
The Spill Killer has two L-shaped covers that attach to a butterfly or frost frame. They seal the edges to prevent light leaks. This design removes shadows caused by fabric ties, bungee cords, or frame structures. It ensures a clean diffusion setup without distractions.
Each Spill Killer is reversible, with a black side to block light and a white side for softer light control. This flexibility helps gaffers and cinematographers quickly adjust their lighting setups for different scene requirements.
The attachment system features integrated magnets sewn into the fabric, ensuring a secure grip without damaging diffusion, bounce, or flag materials. Unlike traditional methods involving clamps or adhesive solutions, the Spill Killer attaches effortlessly and leaves no marks or residue.
For ease of transport and storage, the Spill Killer folds neatly into its included pouch, making it a practical addition to any lighting kit. Setup and removal take only moments, enhancing efficiency on fast-paced film sets.
