Which lighting approach is more efficient?

Lighting the environment first is an efficient approach because it sets the overall atmosphere and context for the scene. By establishing the environmental lighting, filmmakers can create a baseline for the ambient light characteristics that the talent will be working within. This helps ensure that the talent's lighting will harmonize effectively with the surroundings, resulting in a more cohesive look in the final shot.

When the environment is lit first, it allows for a greater understanding of how different light sources interact, such as sunlight, practicals, and available light. This foundational aspect is crucial for creating dynamic contrasts and ensuring that the actors are effectively illuminated without overshadowing or conflicting with the background. Efficient lighting contributes to time management on set, allowing for adjustments and refinements to the talent's lighting based on how they interact with the already established environment. This approach often leads to enhanced visual storytelling, as it maintains a consistent and believable aesthetic throughout the film.
