Learning about light and Back Button Focus

The next 4 weeks my friend and I are working on a few projects. We are both trying to learn our cameras, and have completed the shooting 101 class. This week i'm working on inside lighting, and reading articles, youtube veidos etc. I also recently changed my settings on my camera to utilize back button focus. So far, BBF is kinda amazing, I have more shots in focus then not which is a big change!
