Key light: The key light is the main source of light that illuminates the subject. It is typically positioned at a 45-degree angle to the subject and serves to highlight the face and create depth and dimension.

Fill light: The fill light is used to soften shadows and fill in any dark areas on the subject's face. It is typically positioned on the opposite side of the key light and is softer and less intense.

Background light: The background light is used to illuminate the background and separate the subject from the surroundings. It is typically positioned behind the subject and is used to create a sense of depth and dimension.

Hard light vs. soft light: Hard light creates sharp shadows and can be used to create contrast and drama. Soft light, on the other hand, creates more diffuse shadows and can be used to create a softer, more natural look.

Color temperature: The color temperature of the light can also impact the look and feel of the interview. Warm light, with a color temperature of around 3200K, can create a cozy and inviting atmosphere, while cool light, with a color temperature of around 5600K, can create a more energetic and vibrant atmosphere.

Overall, lighting an interview requires careful planning and attention to detail to create the desired look and feel. By carefully positioning and adjusting the key, fill, and background lights, as well as considering the color temperature and intensity of the light, videographers can create a visually appealing and professional-looking final product.
