• Natural lighting primarily sourced from sunlight varies in color temperature throughout the day
  • Warmer tones during sunrise and sunset (golden hour)
  • Cooler tones during midday (blue hour)
• Natural light intensity and direction change with time and weather conditions creates realistic and organic look
• Artificial lighting controlled by the filmmaker using various light sources
  • Tungsten lights produce warm, orange-tinted light
  • HMI lights emit daylight-balanced, blue-tinted light
  • LED lights offer adjustable color temperature
• Artificial lighting consistent and predictable allows for precise manipulation of shadows, highlights, and contrast can create stylized or surreal effects

Natural light advantages and challenges

• Natural light enhances realism and authenticity captures unique and ephemeral moments flattering for skin tones and textures
• Natural light saves time and money on lighting setup
• Challenges of natural light include inconsistency and unpredictability
• Limited control over intensity, direction, and color temperature with natural light
• Natural light requires careful planning and scheduling around weather and sun position may necessitate additional equipment (reflectors, diffusers) to modify the light

Combining natural and artificial light

• Assess the available natural light and its qualities determine the desired mood, atmosphere, and visual style of the scene
• Use artificial lights to supplement, balance, or contrast with natural light
  • Fill lights soften shadows and reduce contrast
  • Backlights separate subjects from the background and add depth
  • Practical lights (lamps, candles) motivate light sources within the scene
• Match the color temperature of artificial lights to the natural light using gels or filters to adjust the color
• Maintain consistent light direction and quality when combining sources
• Adjust camera settings (white balance, exposure) to ensure proper color rendition and exposure

Impact of lighting on scene authenticity

• Natural lighting enhances realism by mimicking real-world conditions captures the subtle variations and nuances of sunlight evokes a sense of time, place, and atmosphere suitable for documentaries, realistic dramas, and outdoor scenes
• Artificial lighting allows for creative control and stylization can create a heightened sense of reality or surreal effects emphasizes certain elements, emotions, or symbolism appropriate for genres like film noir, science fiction, or fantasy
• Combining natural and artificial lighting balances realism and artistic intent maintains the authenticity of the setting while guiding the viewer's focus enhances the visual narrative and emotional impact of the scene requires careful consideration of the story, genre, and intended audience
