The dominant subject in photography is the main subject in a picture placed at the center of the frame so that there is space at the top and at the bottom. The space at the top is twice as much as the space at the bottom. In order to make your main subject dominate the scene, one should make his or her main subject occupy the whole photo. However, in order to put emphasis on the dominant subject in photographs, some other aspects should be considered as well . Placement of the elements from the picture, light and tones can be very helpful to make the main subject or two main subjects dominate the scene.
