Color temperature
- [Instructor] 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, and 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 with different colors. At a lower temperature, it would glow in orange, it would be a…
