My favorite photo is the one where the boy is pouring a light green and light blue to make a purple outcome .

I picked this photo because i really like  the concept of chemistry and then seeing that it could make that kind of outcome just makes me can't wait to do chemistry when I'm older 

The rules of photography that was in this picture i say balance because there is nothing taking away from the actual photo  and i would say simplicity because you can see that he is in the classroom but it would just be weird if he was at home doing this it would just be boring. But because that he  in the classroom has a better effect on people.
