Sparklers would be a cool example of life for this project. Again, an awesome mood is set by it's own light. And everything els could be edited to be dimmer to draw out the rich color and light of the sparkler.
Contrast: This photgraph is a wonderful example of contrast. this photo shows two diffrent eliments and puts them together. the black park with the red umbrella in the middle creates a contrast of color creates a visual clarity.
I like this picture because the sparkler in the jar are the main focal point because the background is dark. I also like this picture because the jar if only taking a third of the picture but the sparkler is centered.
