The rule of thirds is one of the first things a photographer learns when taking a beginning photography class. When done properly it does produce a balanced and interesting shot that is pleasing to the eye. When applying the rule of thirds while taking a photo, imagine a grid of 9 squares, like the tic tac toe game. Newer cameras have this setting to take the guess work out of composing to automatically help you. When composing your photo through the view finder you focus your subject either on the left one third of the photo or the right one third of the photo with the lines being your guide. When viewing a photo studies have shown our eyes naturally go to either of the intersecting points rather than in the center of the shot.
Now that you have the basic understanding of the rule of thirds, like many things Rules Are Meant To Be Broken!! I took this photo on a recent field trip with my photo club at Ybor City, in Tampa FL. Wandering through the streets several of us spotted some fun street art behind some buildings in the alley. I thought this was a perfect example of Breaking The Rule Of Thirds, centering the red chair under the art with the other chairs along the sides.
