What was remarkable about Gance's filmmaking techniques?

Gance's filmmaking techniques are particularly notable for their innovative use of moving cameras, color tinting, and split screens. His approach significantly advanced the visual language of cinema during the silent film era. By utilizing moving cameras, Gance created a dynamic viewing experience that brought a sense of immediacy and emotion to the storytelling. Color tinting, although not as common in silent films, added a layer of visual depth and helped convey mood and atmosphere, enhancing the emotional impact of the scenes.

The split screen technique, or "polyvision," which Gance pioneered, allowed him to show multiple perspectives simultaneously—an innovative narrative device that expanded visual storytelling in ways that had not been explored before. This creative experimentation set a precedent for future filmmakers and paved the way for more complex cinematic techniques, influencing the evolution of film as an art form.

In contrast, options focusing on static cameras or exclusive use of natural lighting do not accurately reflect Gance's groundbreaking style, as he was known for actively exploring new visual techniques rather than adhering strictly to traditional methods. Similarly, while innovative editing is important, the specific combination of moving cameras, color tinting, and split screens distinguishes Gance's unique contributions to the craft of filmmaking.
