Lighting setup using three distinct light sources to illuminate a subject from different angles
Creates visual depth and dimension by controlling shadows and highlights on the subject
Enhances the subject's features and separates them from the background
Allows for consistent, professional-looking lighting across various shooting conditions
Key components
Key light provides primary illumination and sets overall exposure
Fill light softens shadows created by the key light
Back light (rim light) separates subject from background and adds depth
Light stands, diffusers, and reflectors support the primary light sources
Historical context
Originated in early Hollywood film studios to overcome limitations of early film stocks
Evolved from theatrical lighting techniques adapted for motion picture cameras
Standardized in the 1930s and 1940s as film technology improved
Remains a fundamental technique in modern digital filmmaking and video journalism
Key light
Primary light source in three-point lighting setup establishes overall exposure and mood
Crucial for video journalists to master as it significantly impacts the visual narrative
Requires careful consideration of subject matter and intended emotional tone of the story
Placement and angle
Typically positioned 15-45 degrees off-camera axis
Elevated 15-45 degrees above subject's eye level
Placement determines shadow direction and facial modeling
Adjustments made based on subject's features and desired dramatic effect
Intensity and quality
Determines overall exposure and contrast in the scene
Hard light (small source) creates defined shadows and high contrast
Soft light (large source) produces gentle transitions and lower contrast
Intensity balanced with camera settings to achieve proper exposure
Common key light types
Fresnel lights offer focused, controllable beams
LED panels provide even, adjustable illumination
Softboxes create diffused, flattering light
Natural light (windows) can serve as key in certain situations
Fill light
Secondary light source in three-point setup complements the key light
Essential for controlling contrast and revealing details in shadowed areas
Allows video journalists to balance dramatic lighting with clear subject visibility
Purpose and positioning
Softens and fills in shadows created by the key light
Typically placed opposite the key light, on the other side of the camera
Can be positioned slightly lower than the key light to maintain natural look
Angle and distance adjusted to control shadow density
Fill light vs key light
Fill light is generally less intense than the key light
Creates a more subtle effect, supporting rather than competing with key
Often diffused or bounced to create softer light quality
Can be adjusted to achieve desired contrast ratio in the scene
Adjusting fill intensity
Controls the overall contrast in the image
Higher fill intensity reduces contrast for a flatter, more even look
Lower fill intensity increases contrast for a more dramatic effect
Fill-to-key ratio typically ranges from 1:1 (flat) to 1:8 (high contrast)
Adjusted based on subject matter and storytelling needs in journalistic contexts
Back light
Third component of three-point lighting separates subject from background
Creates depth and dimension in the image crucial for visual storytelling
Helps define subject's silhouette and adds a professional polish to the shot
Function and location
Positioned behind and above the subject, opposite the camera
Creates a rim of light around the subject's edges
Adds depth by visually separating subject from the background
Enhances hair and shoulder details, adding dimensionality
Separation from background
Intensity adjusted to create a subtle glow or pronounced edge
More effective with darker backgrounds or when subject and background have similar tones
Can be used to suggest environmental context (sunlight, moonlight)
Crucial for maintaining subject clarity in busy or cluttered backgrounds
Controlling back light spill
Use of flags or gobos to prevent light from hitting the camera lens
Adjusting intensity to balance with key and fill lights
Positioning to minimize unwanted reflections or flare
Careful placement to avoid overlighting or creating distracting highlights
Lighting ratios
Numerical relationships between light intensities in three-point setup
Essential for controlling mood, contrast, and overall look of the image
Allows video journalists to maintain consistent lighting across different shots and setups
Key to fill ratio
Expresses relationship between key and fill light intensities
Typically ranges from 1:1 (flat lighting) to 8:1 (high contrast)
Lower ratios (2:1, 3:1) common for interviews and news segments
Higher ratios used for more dramatic or moody scenes
Back light to key ratio
Describes intensity of back light relative to key light
Often ranges from 1:2 (subtle separation) to 2:1 (pronounced rim effect)
Adjusted based on subject's hair color, clothing, and background tone
Higher ratios can create stylized looks (silhouettes, high-key effects)
Achieving desired contrast
Balancing all three lights to create appropriate mood and dimensionality
Using light meters or camera histograms to measure and adjust ratios
Considering subject matter and storytelling goals when setting ratios
Adapting ratios to compensate for different skin tones and clothing colors
Equipment considerations
Selection of appropriate lighting gear impacts both image quality and production efficiency
Video journalists must balance equipment choices with portability and setup time constraints
Understanding various light types and modifiers enables adaptability in diverse shooting scenarios
