  1. 1. LIGHT<br />
  2. 2. LIGHT<br />Hard/Soft<br />
  3. 3. LIGHT<br />Hard/Soft (Contrast)<br />
  4. 4. LIGHT<br />Hard/Soft (Contrast)<br />Warm/Cool (Color)<br />
  5. 5. COLOR OF LIGHT<br />Measured on Kelvin scale<br />
  6. 6. COLOR OF LIGHT<br />Measured on Kelvin scale<br /> Named for physicist William Kelvin, who discovered a block of solid carbon emits light at specific colors depending upon the temperature.<br />
  7. 7. COLOR OF LIGHT<br />Measured on Kelvin scale<br /> Named for physicist William Kelvin, who discovered a block of solid carbon emits light at specific colors depending upon the temperature.<br /> Temp (K) = Temp (c) + 273 (Absolute zero = 0 on Kelvin scale)<br />
  8. 8. COLOR OF LIGHT<br />Measured on Kelvin scale<br /> Named for physicist William Kelvin, who discovered a block of solid carbon emits light at specific colors depending upon the temperature.<br /> Temp (K) = Temp (c) + 273 (Absolute zero = 0 on Kelvin scale)<br />
  9. 9. COLOR OF LIGHT<br />We can also measure light by its wavelength<br />
  10. 10. COLOR OF LIGHT<br />We can also measure light by its wavelength<br /> Visible light occupies the range on the electromagnetic spectrum from about 390 nm to 800 nm.<br />
  11. 11. COLOR OF LIGHT<br />We can also measure light by its wavelength<br /> Visible light occupies the range on the electromagnetic spectrum from about 390 nm to 800 nm.<br />
  12. 12. COLOR OF LIGHT<br />It is helpful to understand that what we call “White Light,” is actually comprised of all colors, at varying wavelengths.<br />Not all colors reflect off all surfaces, and not all colors transmit through materials. <br />
  13. 13. COLOR OF LIGHT<br />It is helpful to understand that what we call “White Light,” is actually comprised of all colors, at varying wavelengths.<br />Not all colors reflect off all surfaces, and not all colors transmit through materials. <br />
  14. 14. COLOR OF LIGHT<br />It is helpful to understand that what we call “White Light,” is actually comprised of all colors, at varying wavelengths.<br />Not all colors reflect off all surfaces, and not all colors transmit through materials. <br />
  15. 15. COLOR OF LIGHT<br />It is helpful to understand that what we call “White Light,” is actually comprised of all colors, at varying wavelengths.<br />Not all colors reflect off all surfaces, and not all colors transmit through materials. <br />
  16. 16. COLOR OF LIGHT<br />Effect of color filtration on Color photography results in a color shift, which should be obvious.<br />
  17. 17. COLOR OF LIGHT<br />Effect of color filtration on Color photography results in a color shift, which should be obvious.<br />How does color filtration affect B&W photography?<br />
  18. 18. COLOR OF LIGHT<br />Effect of color filtration on Color photography results in a color shift, which should be obvious.<br />How does color filtration affect B&W photography?<br />Selective darkening of tonal values based on color of the subject.<br />For instance, a red or orange filter on the camera while shooting black & white, will result in a darkening of blue and green tones, such as the sky, or foliage.<br />
  19. 19. “SOFTNESS” or “HARDNESS” OF LIGHT<br />Relates to the edges of shadows in the scene.<br /> Hard light produces hard shadows<br /> Soft light produces soft shadows.<br />
  20. 20. “SOFTNESS” or “HARDNESS” OF LIGHT<br />Relates to the edges of shadows in the scene.<br /> Hard light produces hard shadows<br /> Soft light produces soft shadows.<br />Natural Light:<br /> Direct sunlight Hard<br /> Late afternoon/Early morning (Magic hour) Soft<br /> Overcast day Soft<br /> Direct sunlight bounced off a bright wall Soft, but likely directional<br /> Direct sunlight bounced off a mirror/window Hard<br /> Open shade Soft<br />
  21. 21. “SOFTNESS” or “HARDNESS” OF LIGHT<br />Relates to the edges of shadows in the scene.<br /> Hard light produces hard shadows<br /> Soft light produces soft shadows.<br />Light modifiers:<br /> Any device utilize to alter or enhance the appearance of light.<br />
  22. 22. “SOFTNESS” or “HARDNESS” OF LIGHT<br />Relates to the edges of shadows in the scene.<br /> Hard light produces hard shadows<br /> Soft light produces soft shadows.<br />Light modifiers:<br /> Any device utilize to alter or enhance the appearance of light.<br /> Reflector cards/panels<br /> Diffusion material<br /> Plastic or fabric sheets<br /> Umbrellas, soft boxes, grids<br /> Gels/filtration<br /> Etc.<br />
  23. 23. “SOFTNESS” or “HARDNESS” OF LIGHT<br />
  24. 24. “SOFTNESS” or “HARDNESS” OF LIGHT<br />
  25. 25. “SOFTNESS” or “HARDNESS” OF LIGHT<br />
  26. 26. “SOFTNESS” or “HARDNESS” OF LIGHT<br />
  27. 27. “SOFTNESS” or “HARDNESS” OF LIGHT<br />
  28. 28. “SOFTNESS” or “HARDNESS” OF LIGHT<br />
  29. 29. “SOFTNESS” or “HARDNESS” OF LIGHT<br />
