Subject placement refers to the position of the subject relative to the frame.

Placing the subject in the center is one method of subject placement but some will argue that when you place your subject in the center of your frame, you divide your image in half. You break up the background and often freeze any action that may be taking place.

Another method is the rule of thirds. With the rule of thirds, instead of dividing your image in half, divide your frame into thirds both horizontally and vertically. The frame that results will have have 4 intersections. By setting your subject directly on one of these 4 intersections, you will be able to keep both your foreground and background interesting.

Another method is the diagonals method. This method states that you should first divide your screen diagonally between any two corners. You should then choose a third corner and divide your screen again so that the resulting line intersects the first at a 90 degree angle. The point where the two lines intersect is where you should place your subject.
