Join Aaron F. Ross for an in-depth discussion in this video Color temperature, part of 3ds Max 2017: Advanced Lighting.
- Our final core concept for Advanced Lighting…is color temperature.…What we perceive as color is actually…wavelengths, or frequencies, of light.…When we see white light…that's a combination of all wavelengths combined at once.…That's considered perfectly white.…But in the real world, light sources…are almost never perfectly white.…But we don't usually notice, because our eyes…adapt really well.…A real-world camera or a 3D rendering needs to be calibrated…to the color of light in the scene to accommodate…for the way our eyes adapt and a camera doesn't.…
We need to tell the camera or the renderer…what our reference white point is.…And to do that, we can provide a color temperature value…which is measured in degrees Kelvin.…These numbers are derived…from a hypothetical black body experiment.…If we took a perfectly black object…and heated it to different temperatures…it would glow at different colors.…At a lower temperature, it would glow in orange.…It would be a "warm" color.…As we increase the temperature…on the hypothetical black body, it will glow white,…
