I'm rendering an outer space scene with a spaceship. I am using 
Lightsys. Are there any particularly good light sources for stars like 
our sun? Right now I am using 6100 color temperature.

Thanks.


Mike

I generally use 6200 (which is fairly identical) for daylight. That 
seems all right to me for space too. It is interesting of course to play 
with the whole range of temperatures (2800-7500) to get different star 
types. I did that in my latest Stranger Moon scene.

The photosphere of our sun is 5772 K, so its color in outer space should 
be somewhat near a black body of that temperature.

However, the white of a computer monitor is quite bluish (daylight 6504 
K), and it seems like colors need to be shifted towards the blue in 
order to look "normal."  Raising the color temperature of the light 
source would accomplish this.
