Rule of Thirds

An object should have an extra spaces left on a picture frame. To determine how big we must spare for an object, simply we can apply the rule of thirds.

Fig.2 shows how the application of this rule. The object is the head light of a train facing opposite.

If you take a shot on an object, first thing you must create imaginary portions of the complete picture in frame. The portions were divided into 9 sections, consist of 3 horizontal and 3 vertical sections. Then put your object on the one third of the whole picture size, hence your object will be appeared in the intersections of the portions.

Some modern digital cameras have the utility to show these gridlines on their screen. A common mistake from amateur are taking their object right in the middle of the frame and leave no space for a "story" to tell.

Fig 2. The Rule of Third

At the sample image above, the main object is the headlight of the opposite train. The object itself would be meaningless if it got too much crop. The composition consist of the main object, which is the headlight and the lines that made by the rails and building structure.
