Rule of thirds:
The rule of thirds is possibly the most well known tool of photographic composition.
An image can become more interesting when its subjects or regions are composed along imaginary lines which divide the image into thirds both vertically and horizontally
The rule of thirds often creates a sense of balance without making the image appear too static. It can add a sense of complexity without making the image look too busy.
There are times when you should break the rules. Rules of composition can and should be broken when the photographer decides to. Breaking the rules doesn't make your images unbalanced or uninteresting.
This image would not have the same impact if i had followed the rule of thirds.
You must learn the rules of design so that you can break them with intention.
