Basic composition in Photography: Rule of Thirds

After going around and reading my friend's entries, I find out that I write too much but not focus to the topic, so I have to change my style T___T

Today, I will write about the Rule of Thirds in Photography. This rule is applied in Photography as the basic knowledge about composition that every Photographer has to know before having any beautiful photos.


These rectangular are divided by two horizontal and two vertical lines (the blue lines). These lines that separate the rectangular into 3 equal area meet together at 4 points (the blue points).
In Photography, these 4 lines are called the 4 strong lines, and the 4 points are named strong points.
To emphasize the object, the photographers have to set the object as close as possible (or match) to the 4 strong line and 4 strong points.
I will use my photos to illustrate how this rule is applied into photography:


When I took that picture, I want to emphasize the flowers therefore I tried to set the flowers on the strong points and the strong line instead of putting them into the middle of the photo.

Okay, this picture was not taken by me (of course! because I was the main character in this picture^). As you can see, the 2 models were posed on the horizontal strong line therefore they are emphasized effectively. Moreover, the other horizontal strong lines also highlight the sky above.

To sum up, people usually assume that putting the objects into the middle of the picture will highlight the objects but it is not correct.
