Back Lighting.

 

In this picture, there is a very pretty sunflower. I found it in my friend's backyard. You can even see her house in the background. Th light is coming from directly behind it, and it really lights up the flower petals. 

I chose this picture because it was a very good representation of back lighting. When  I was taking this picture, I was thinking about different angles I could take this picture. The way the sun hit the petals really caught my eye when I took this. 

In this picture, of course, there is back lighting. There is also rule of thirds and repetition. It is rule of thirds because if you divide the picture into thirds, the middle of the flower would be in the third. It is repetition because the petals repeat.
