Probably one of the most basic tips concerning composition of a photo is the use of thirds. Think of the scene you are viewing through your camera as being placed on a tic-tac-toe board. The most important portion of the picture should be where two of the lines intersect. For example, if the horizon falls in the center of the picture the viewerâ€™s eye is in conflict because it doesnâ€™t know whether to look at the sky or the ground. The photo is more interesting when people, objects, etc. are placed using the principle as well.
Bobby, my husband, drives me around for photo shoots and now understands why I never centered things when he was helping me hang decorations or pictures on the wall. The same principle of using thirds applies in all forms of art.
