Re: Sunlight is not white
Ok, the key part you are missing is that white balance is subjective. There is no objectively correct white balance, our cones and rods are not a uniform sensitivity, and even if they were, as the wave length changes, the energy of the photons change. So when we are working out how to treat our images that means a lot of… -
Re: Sunlight is not white

The effects are limited, but it is actually a physically understood phenomena. http://www.moillusions.com/black-and-white-spanish-castle-in Doing a bit more reading on it just now, turns out that while the brain has part of the blame, most of it is in the retina. the cones in our eye… -
Sunlight is not white
Hello. I was looking into what's the "official" colour of sunlight. Is it yellow, is it white? As it is, the sunlight that touches the surface of objects on earth can be slightly yellow or warm, depending on the time of day and the altitude of your scene. This can be found through observation, but I was looking for a… -
Re: Sunlight is not white
Your own source contradicts you btw. http://solar-center.stanford.edu/SID/activities/GreenSun.html I would also argue that the effect is negligible when it comes to rendering because while blue light is diffused, it essentially adds to the ambient component, so what is received by a spectrograph pointing directly at the… -
Re: Sunlight is not white
I agree. There's a moment in the Practical Light and Colour DVD when the author comments on a backlit picture, stating that you can see the warmth of the sun, the falloff of the bounced light and the coldness of the shadow that comes from the blue skylight:
