- 1. Introduction to Lighting & Techniques
- 2. Introduction Films consist of pictures and sound. The pictures come from cameras, but cameras need light to see. All around us, there is plenty of light “accidentally”, from ambient daylight, room lights, etc.
- 3. Introduction On location, it is the lighting team’s job to: 1. Use and supplement, or 2. Eliminate the “accidental” light In the totally controlled studio environment, all light has to be provided for the cameras
- 4. Arri Fresnel 1Kw Spot Light Provides light to a specific spot Barn doors can be adjusted to: 1. Limit light 2. Reduce shadows 3. Overlap adjacent lights Produces a lot of heat
- 5. Kino Flo Soft, flood light Provides light to a large area Produces less heat Fits into cramped areas
- 7. Three-point Lighting Most commonly used setup Building block Key light Fill light Back light
- 8. Key Light Brightest light Most important Reveal surface form Principal shadow One side of the camera
- 9. Fill Light Less intensity Diffuse (soften) Opposite side Reduce shadows by key light
- 10. Three-point Lighting Combination Depth & Separation 3 Dimensional Separate background from subject
- 11. Direction of Lighting Front Edge (side) Back Under
- 12. Frontal Lighting From camera’s viewpoint Reduces modeling and texture Diminishes age wrinkles Avoids shadows
- 13. Edge Lighting Emphasizes texture and contours Highlights objects
- 14. Back Lighting Directly behind subject Often from high position Halo effect Illuminate & separate outline
- 15. Under Lighting Inverted facial modeling Mysterious Ghostly
- 16. Lighting Mood Lighting helps to establish the mood of your story. Changing the angle, intensity, and colour of your lights can dramatically alter the mood of a scene
- 17. Flat Lighting Low contrast Reveals all details Little or no shadows No background separation Boring
- 18. Modeled Lighting High contrast Tonal graduation Shadows formations Three-dimensional illusion
- 19. Atmospheric Lighting Mood lighting Support the atmosphere or environment Normally associated with darker images Use of practical lights
- 20. Silhouette Lighting Back lighting Brighter background No or little subject detail
- 21. Common Lighting Terminology Ambient light The light already present in a scene, before any additional lights are added. Incident light Light seen directly from a light source (sun, lamp, etc). Reflected light Light seen after having bounced off a surface.
- 22. Common Lighting Terminology Colour temperature A standard of measuring the characteristics of light, measured in degrees Kelvin. Contrast ratio The difference in brightness between the brightest white and the darkest black within the image. Key light The main light on the subject, providing most of the illumination and contrast.
- 23. The Correct Way of Lighting There is never a correct or definite way. There is always scope for interpretation and trail & error in lighting.
- 24. The Correct Way of Lighting The best way is to ask these 2 questions: 1. How do I light the scene logically and realistically? 2. Where is the light for the scene coming from?
- 25. Angle of Shine The imagined source of light for a scene representing the sun shining downwards What is your angle of shine in order to recreate the light from the sun?
- 26. Managing Shadows In the natural world, objects often only cast one defined shadow How do you light your shot to achieve one clear defined set of shadows?
