After you've chosen your vantage point, select the lens that will allow you to include only as much of the scene as you want. Perspective is the interrelationship between a subject and its surroundings as seen from your vantage point. The intersections of these lines are all strong areas in the frame. If there's more than one element in the image, placing your main subject off center where the lines intersect can make the composition more balanced and pleasing to the eye. If, on the other hand, you're dealing with a single element of interest.
Faces are a good example.
There are occasions, of course, when absolute symmetry is called for. These subjects are best placed in the center position. If you're shooting animals or people, always make certain they're looking into the frame give them some space in the direction they are looking, to give the image a logical framework. If the most effective The upper third of your subject is looking out of the frame, you'll lose any sense of the subject's involvement with its environment. Lines can be absolute, such as horizons, trees, or fence posts, or they can be suggested, as a series of rocks, flowers, or even shadows that draw the eye to the main subject.
