Shooting a film set in the early 17th century with candlelight as the primary source is among the most technically demanding challenges in independent cinema. On Rose, director Markus Schleinzer's Berlinale 2026 entry, cinematographer Gerald Kerkletz faced that challenge directly. Sandra Huller stars in the period drama and won the Silver Bear for Best Leading Performance. Kerkletz's solution: prototype LED candles, custom-made for the production, that provided the visual language of candlelight without the constraints and dangers of actual flame.
Period films that commit to candlelight as historically accurate source lighting are rare because the technical challenges are severe: real flames cannot be reliably controlled; they create unpredictable hotspots; they make it nearly impossible to repeat takes with consistent light; they pose safety risks in enclosed interiors. Most period films default to hidden modern lighting hidden to mimic candlelight. Kerkletz made a different choice: he worked with engineering to create prototype LED candles that could deliver the specific color temperature and quality of actual candlelight while being controllable, repeatable, and safe.
This decision speaks to how seriously the production took visual authenticity. Filming in the early 17th century is not just a location decision; it's a commitment to how light moves through the world of 1600. Candlelit interiors have a specific quality—small pools of warm light, hard shadows, areas of deep darkness just beyond the light's reach. The visual grammar is fundamentally different from modern lighting. Kerkletz refused to approximate this. He built the tools to achieve it precisely.
The result has been described by critics as 'a gorgeously shot, black and white masterpiece.' ScreenHub Australia called it a 'joint favourite at the Berlinale.' The black and white cinematography compounds the period commitment: 17th-century interior spaces had no color as a visual marker. They had light and shadow, texture and depth. Rendering them in black and white with prototype LED candles as the light source creates an image that feels archaeologically accurate—not historically reconstructed but historically imagined with rigor.
For cinematographers interested in how to maintain period authenticity in visual language, Kerkletz's approach offers a crucial lesson: you don't compromise on the light source. If the story is set in candlelight, you commit to lighting with candles, even if that requires custom engineering. The prototype LED candles were not off-the-shelf solutions. They were built for this film's specific visual requirements.
This kind of production commitment—building technology rather than working around constraints—is increasingly rare in independent cinema. Kerkletz and Schleinzer chose to do it, and the cinematography reflects that choice. Every shot earned its place through technical precision and historical commitment.
Prototype LED candles for a 17th-century period drama. The technology was built for one film's lighting requirement. That is what period commitment looks like.
