Why is lighting considered significant in video production?

Lighting plays a crucial role in video production primarily because it sets the mood and ensures clarity. The way a scene is lit can dramatically influence the emotional tone of the piece; for instance, soft lighting might evoke a warm, intimate feeling, while harsh lighting can create a sense of tension or unease. Additionally, proper lighting is essential for visibility and understanding what is happening on screen. It helps to define the subject and creates a visual hierarchy, guiding the viewer's attention to the most important parts of the frame.

While enhancing visual effects and potentially reducing shooting time might also hold some truth, these factors are secondary compared to the foundational role lighting plays in establishing mood and clarity. The determination of a film's runtime is unrelated to lighting; it is influenced by the script, pacing, and editing, rather than how a scene is lit. Therefore, the importance of lighting in terms of mood and clarity solidifies its critical role in the success of any video production.
