6. COLOR OF LIGHT Measured on Kelvin scale Named for physicist William Kelvin, who discovered a block of solid carbon emits light at specific colors depending upon the temperature.
7. COLOR OF LIGHT Measured on Kelvin scale Named for physicist William Kelvin, who discovered a block of solid carbon emits light at specific colors depending upon the temperature. Temp (K) = Temp (c) + 273 (Absolute zero = 0 on Kelvin scale)

9. COLOR OF LIGHT We can also measure light by its wavelength
10. COLOR OF LIGHT We can also measure light by its wavelength Visible light occupies the range on the electromagnetic spectrum from about 390 nm to 800 nm.
11. COLOR OF LIGHT We can also measure light by its wavelength Visible light occupies the range on the electromagnetic spectrum from about 390 nm to 800 nm.
12. COLOR OF LIGHT It is helpful to understand that what we call “White Light,” is actually comprised of all colors, at varying wavelengths. Not all colors reflect off all surfaces, and not all colors transmit through materials.

16. COLOR OF LIGHT Effect of color filtration on Color photography results in a color shift, which should be obvious.
17. COLOR OF LIGHT Effect of color filtration on Color photography results in a color shift, which should be obvious. How does color filtration affect B&W photography?
18. COLOR OF LIGHT Effect of color filtration on Color photography results in a color shift, which should be obvious. How does color filtration affect B&W photography? Selective darkening of tonal values based on color of the subject. 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.
19. “SOFTNESS” or “HARDNESS” OF LIGHT Relates to the edges of shadows in the scene. Hard light produces hard shadows Soft light produces soft shadows.
20. “SOFTNESS” or “HARDNESS” OF LIGHT Relates to the edges of shadows in the scene. Hard light produces hard shadows Soft light produces soft shadows. Natural Light: Direct sunlight Hard Late afternoon/Early morning (Magic hour) Soft Overcast day Soft Direct sunlight bounced off a bright wall Soft, but likely directional Direct sunlight bounced off a mirror/window Hard Open shade Soft
21. “SOFTNESS” or “HARDNESS” OF LIGHT Relates to the edges of shadows in the scene. Hard light produces hard shadows Soft light produces soft shadows. Light modifiers: Any device utilize to alter or enhance the appearance of light.
