My last assignment for my class was about the "rules of composition." We had to submit 4 that followed the rules, and 2 that successfully broke them. It was actully really hard for me to think of a good photo that would break the rules.
Here are the ones I submitted:
This one breaks the rule of contrast, but it follows the "rule of thirds." I hope she'll accept it. :)
This one breaks the rule of balance. --also, I guess it breaks the rule of simplicity, but I didn't think of that until now.
This one follows the rule of simplicity, and also maybe contrast (orange against blue), and maybe "leading lines"
