CCT = Correlated Color Temperature (6500K, etc.)


CIE Illuminants =>

  • General lighting conditions (when taking a picture, or displaying one).
  • Spectral characteristics similar to natural light sources
  • Reproducible in the laboratory


1931 Illuminants:

  • Illuminant A = Typical Incandescent Light
  • Illuminant B = Direct Sunlight
  • Illuminant C = Average daylight from total sky (ambient sky light)


1963 Illuminants (more accurate daylight conditions):

  • Illuminant D followed by the first 2 digits of the CCT (e.g. D65 = D 6500K)
