Lighting intro -_day_9.ppt[1]

  1. 1. Introduction toLighting & Techniques
  2. 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. 3. Introduction On location, it is the lighting team’s job to:1. Use and supplement, or2. Eliminate the “accidental” light In the totally controlled studio environment, all light has to be provided for the cameras
  4. 4. Arri Fresnel 1Kw Spot Light Provides light to a specific spot Barn doors can be adjusted to:1. Limit light2. Reduce shadows3. Overlap adjacent lights Produces a lot of heat
  5. 5. Kino Flo Soft, flood light Provides light to a large area Produces less heat Fits into cramped areas
  6. 6. Redheads & Blondies
  7. 7. Three-point Lighting Most commonly used setup Building block Key light Fill light Back light
  8. 8. Key Light Brightest light Most important Reveal surface form Principal shadow One side of the camera
  9. 9. Fill Light Less intensity Diffuse (soften) Opposite side Reduce shadows by key light
  10. 10. Three-point Lighting Combination Depth & Separation 3 Dimensional Separate background from subject
  11. 11. Direction of Lighting Front Edge (side) Back Under
  12. 12. Frontal Lighting From camera’s viewpoint Reduces modeling and texture Diminishes age wrinkles Avoids shadows
  13. 13. Edge Lighting Emphasizes texture and contours Highlights objects
  14. 14. Back Lighting Directly behind subject Often from high position Halo effect Illuminate & separate outline
  15. 15. Under Lighting Inverted facial modeling Mysterious Ghostly
  16. 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. 17. Flat Lighting Low contrast Reveals all details Little or no shadows No background separation Boring
  18. 18. Modeled Lighting High contrast Tonal graduation Shadows formations Three-dimensional illusion
  19. 19. Atmospheric Lighting Mood lighting Support the atmosphere or environment Normally associated with darker images Use of practical lights
  20. 20. Silhouette Lighting Back lighting Brighter background No or little subject detail
  21. 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. 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. 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. 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. 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. 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?
