1. Chapter 6.6 Lighting

2. Digital Lighting: Fundamentals
Lights define 3-D form in a 2D medium
Bring out surface qualities
Accent Form
Lighting creates focus
Luminance is relative to RGB value range
Light can draw viewers attention
Pools of brighter light
Spots of distinct colors

3. Digital Lighting: Fundamentals
Lights create the Mood of a scene
Cool, Warm or Hot color schemes
Brightly lit vs. Dark shadowy lighting
Soft vs. Hard shadows

4. Digital Light Models Point Light Spotlight Directional Light
Area Light

5. Ambient vs. Reflected Light
Digital Ambient Light
Adds an RGB value to all surfaces
Reduces overall contrast
Reflected Light (digital: Radiosity)
Real-world ambient light
Created by light bouncing off surfaces
Surface color and reflectivity affect light

6. Shadows Spatially orient objects Dispersion of shadows affect mood
Soft shadows
Generally brighter
More subtle compositional element
Hard shadows
Stronger contrast
Interesting compositional potential

7. Light Effects Lenses flairs and light bloom
Atmospheric Fog; volumes of light
Glowing light sources
Self-illuminated textures

8. Summary Lighting is essential to composition Digital Light models
Legibility of detail
Determining emotional state
Directing the players attention
Digital Light models
Different from real world light
Light for good composition
Light doesn’t always come from a visible source
