Transcript of "EMC 3130/2130 Lecture Six - Lighting Part 1 Light"

  1. 1. Lighting Lecture
  2. 2. 1. Light
  3. 3. 1. Light 2. Lights
  4. 4. 1. Light 2. Lights 3. Lighting
  5. 5. 1. Light
  6. 6. Intensity (brightness) affects exposure, and is affected by exposure. Light - Intensity
  7. 7. Intensity (brightness) affects exposure, and is affected by exposure. Light - Intensity http://youtu.be/NXAfy5rvY8M
  8. 8. Intensity (brightness) is also effected by distance and power (wattage) Light - Intensity
  9. 9. How to maximize existing light: • Move the subject closer to a light source • Open up the aperture • Boost camera gain or select a higher ISO • Increase the available lighting (turn on some lights, open the curtains) • Add lighting instruments Light - Intensity
  10. 10. How to minimize existing light: • Move the subject away from the light, or into the shadows • Close down the aperture • Add neutral density to the lens or the light source • Select a lower ISO • Switch off or block off existing lighting (turn off lights, close curtains or blinds) Light - Intensity
  11. 11. How to minimize (control) light from professional light sources: • Switch off some lights • Use lower power light sources • Use a dimmer (watch out for effect on color temperature) • Diffuse the light • Move the light farther away • Add neutral density to the light • Flood the light • Bounce the light Light - Intensity

  14. 14. Hard, Harsh and Direct, such as sunlight. Light is concentrated, traveling from the light source or the filament of the lamp directly to the subject. Shadows are sharp. Light - Quality
  15. 15. Hard, Harsh and Direct, such as sunlight. Light is concentrated, traveling from the light source or the filament of the lamp directly to the subject. Shadows are sharp. Pros • Highly directional • Sharp shadows exaggerate texture • Intensity does not “fall off” appreciably with distance • Bold, strong, dramatic Light - Quality
  16. 16. Hard, Harsh and Direct, such as sunlight. Light is concentrated, traveling from the light source or the filament of the lamp directly to the subject. Shadows are sharp. Cons • Shadows can be distracting • High contrast creates harsh effect • Textures may not be flattering, such as the irregularities in a subject’s skin • Coverage is restrictive; more sources may be needed • With more than one source, multi-shadows may be generated (All these cons can also be pros) Light - Quality
  17. 17. Soft and diffused, such as a cloudy day. Light comes from a “broad” source,” reflected off or spread out though a translucent substance. Shadows have soft edges. Light - Quality
  18. 18. Soft and diffused, such as a cloudy day. Light comes from a “broad” source,” reflected off or spread out though a translucent substance. Shadows have soft edges. Pros: • Subtle, delicate, flattering shading • Less distracting shadows • Softens textures, such as skin • Details more visible in the shadows • Covers a wide area; spreads and wraps around surfaces (All these pros can also be cons) Light - Quality
  19. 19. Soft and diffused, such as a cloudy day. Light comes from a “broad” source,” reflected off or spread out though a translucent substance. Shadows have soft edges. Cons: • Can be flatter than hard light • Spreads and wraps and can be more difficult to control • Softens textures, such as skin • Details more visible in the shadows • Covers a wide area • Falls off quickly (All these cons can also be pros) Light - Quality
  20. 20. Source: Hard and Soft Light - Quality
  21. 21. Source: Hard and Soft Light - Quality http://youtu.be/g1weO6yEhMc
  22. 22. Light - Contrast Low High The difference between the brightest and darkest areas of an image
  23. 23. Light - Contrast Dynamic Range / Latitude: Dynamic range describes the ratio between the smallest and largest possible values of a changeable quantity (such as light). Latitude (used interchangeably with dynamic range) is the ability of the film or video sensor to capture details in the lowest end of the tonal spectrum (i.e. dark shadows) while at the same time capturing details in the highest and brightest end of the tonal spectrum (i.e. a bright sky). So latitude effects how much detail can be seen in the shadows and the brightest areas of the image.
