Can light create darkness?

My essential question for this project was if light can create darkness. I chose this because 1) I couldn't think of anything better, 2) because I like the idea/challenge of capturing light in a painting, and 3) because I wanted to combine the ideas of cold, loneliness and light. (My original question was about cold.) I found a picture of a street lamp on the side if a building for inspiration and decided that besides tweaking a few things, I would use that picture. I ended up changing my mind after doing the back ground, and decided to just do a single light bulb. I like the way it turned out, and I think it's one of my favorite pieces that I've done.
