I did the sunset scene for the lighting course in cycles. I ended up using two sun lamps, The first lamp was at kelvin 3200, and I did 10 power, the second I did 1500 kelvin at 20 power. I wanted a bit more red to the lighting than was normal. Then I added a sky texture at 5 power, for just a bit of extra color.
I also did a volume cube at .05 volume around the whole room, to soften things just a tad and add some setting sun rays.
It's amazing how much lighting can change the feel of a scene. Also, great course so far. Though I really need a faster graphics card, lol. 15 mins for a render is too long.
Anyway, I'm pretty happy with the overall effect. But interested in hearing any feedback.
