11.3 Practical vs. Motivated Lighting in Set Design

Lighting design in set production is all about creating believable environments. Practical lights, like lamps and candles, add realism to scenes. Motivated lighting mimics natural sources, while diegetic lighting includes any light that exists in the story world.

Non-diegetic lighting adds artistic flair, creating dream sequences or emotional states. Ambient lighting sets the overall tone, simulating different times of day. Balancing these techniques helps create immersive atmospheres that support the story and captivate audiences.

1 of 3

• Practical lights function as visible light sources within the scene
• Includes lamps, candles, overhead fixtures, and other built-in set elements
• Enhances realism by providing believable illumination sources
• Can be used to create depth and visual interest in the set design
• Offers opportunities for creative placement and styling to support the overall aesthetic
• Allows for dynamic lighting changes during scenes (characters turning lights on/off)

Motivated and Diegetic Lighting Techniques

• Motivated light sources mimic natural or practical light origins not visible in the frame
• Simulates light coming from windows, fireplaces, or off-screen practical sources
• Diegetic lighting refers to any light source that exists within the world of the story
• Includes both practical lights and motivated sources that characters can interact with
• Creates a sense of authenticity and logical lighting for the environment
• Can be used to establish time of day, location, or mood within the scene

Integrating Lighting into Set Design

• Set-integrated lighting incorporates light sources directly into the set construction
• Involves collaboration between lighting designers and set designers
• Can include hidden LED strips, backlit panels, or custom-built practical fixtures
• Allows for seamless integration of lighting elements with the overall set aesthetic
• Provides opportunities for creative lighting solutions that enhance the production design
• Requires careful planning to ensure proper power distribution and heat management

Non-Diegetic and Ambient Lighting

Non-Diegetic Lighting Techniques

• Non-diegetic lighting refers to light sources that do not exist within the story world
• Used primarily for artistic or atmospheric effects rather than realistic illumination
• Includes colored gels, gobos, and other stylized lighting techniques
• Can be employed to create dream sequences, flashbacks, or heightened emotional states
• Allows for greater creative freedom in manipulating the visual mood of a scene
• Must be used judiciously to avoid breaking the audience's suspension of disbelief

Ambient Lighting and Atmosphere Creation

• Ambient lighting establishes the overall light level and tone of a scene
• Provides a base layer of illumination upon which other lighting elements are built
• Can be used to simulate different times of day or environmental conditions
• Includes techniques like soft fill lights, bounce lighting, and diffused sources
• Helps create depth and dimensionality in the set by controlling shadow density
• Contributes to the overall mood and atmosphere of the production design

Maintaining Lighting Continuity in Production

• Continuity in lighting ensures consistency across shots and scenes
• Requires careful documentation of lighting setups for each scene and location
• Involves matching color temperature, intensity, and direction of light sources
• Considers changes in natural light when shooting over extended periods
• Utilizes continuity photos and lighting plots to maintain consistency during reshoots
• Balances the need for consistent lighting with artistic choices for scene transitions
