The movie Tron is lit very darkly, with the most light coming from the characters themselves. It is an interesting way to make them visible in spite of little ambient light, and the eerie light cast up on their faces gives this movie a more grim outlook.
Strangely, in this picture of the Orion Nebula, it is not differing intensity or direction that helps build a composition, but instead my eye is drawn to differing color.
The color and intensity of the light off of lava makes all else barely visible. The mood I get is as if I were watching the formative moments of the planet.
While set in the same snowy environment of post 26, this post contains a red tongue, and yellow feathers on the penguins in the background which help to raise the mood to that of a dance. Also the texture of the feathers reminds me of a coat which helps to combat my cold feeling.
Here's another pumpkin. I think that the direction of light, coming out of the dragon, really illustrates that there is a fire within the dragon. Also, notice that the cool patterns in the scales are only visible because of the light near them.
