If every reading was 5800, it would to me too. 5800 or so makes sense because that's the temperature of the sun's surface. But to have all those histogram readings at the 25000 temperature range does not make sense to me. We haven't explained where all the net extra blue light came from (i.e...
But the paper also says:
As it indicates, clear skies occur ;3.5 times more frequently in Granada than do overcasts. Yet perhaps surprisingly, Fig. 4 shows only subtle differences in inverse-CCT frequency distributions for these two extreme sky states.
So fair enough, the mean CCT for...
I honestly don't think the conventional wisdom type explanations really explain things, but thanks for giving it a shot.
Well, I guess that's the common sense mechanism that we expect or that we have been told, but the data suggests otherwise. The histogram attachment shows there is little to...
In Color and spectral analysis of daylight in southern europe, there is a histogram (see attached) that suggests CCT is uncorrelated with the existence or absence of cloud cover.
Very curious if anyone knows of the atmospheric physics that explains this, or can point me in the right...
Thank you for your reply. That's a general photographer's website, I have basically described some of the underlying theory behind some of those ideas. However, the specific reason for why CCTs reach 25,000 in daylight is not really touched in that article. There are a lot of photography...
A blackbody radiator emits radiation across the entire radiation spectrum. The "temperature" of the blackbody radiator (measured in kelvin) can be directly calculated from the peak wavelength of its radiation using http://en.wikipedia.org/wiki/Wien's_displacement_law"]Wien's[/PLAIN]...
