I have seen in some LED Light panels designed for video and film production the addition of AMBER leds mixed with the white emitters used on the panels. They are able to tune the panel to work best as a daylight source by adjusting the amount of amber light mixed in with the other emitters. I do not know how much latitude this gives them. There is no doubt that it is very possible to make a human being look terrible (on film and tv) and in person based simply on how you light them.
I find it interesting how different all of this becomes when transitioning from standard daylight based lighting to "digital" lighting using leds as the primary light source. One thing which is almost universally true in making this transition is that Led's do not have anywhere near the same OOOMPH as HMI's or tungsten lighting.
I tend to look at this from this perspective because this is where I see the technology being implemented ....slowly..
More and more interior lighting will be based on Leds. IMHO it is important that when people are lit in this way they do infact look natural and good. I am sure this is the goal of the manufactures of the emitters and the fixtures for LED interior lighting projects.
