This tree is on the Fresno State University walkway. I wanted a shot looking up at the branches from along the trunk (which I got). I took an eight second exposure and this green apeared on the trunk and red in the branches. The red I could understand since I knew the leaves were redish, but the green I didn't. Later than night I was talking to a friend who works at a news station. He was mentioning that they changed some flourescent lights because there was too much green. I then realized that the lights there were flourecent. So with that combo, I thought this came out really well, and somewhat unplanned.
