Balance
Balance:
Balance implies that the visual elements within the frame have a sense of weight. Large objects generally weigh more than small objects and dark objects weigh more than light colored objects.
The large bright disc of the sun is balanced by the black silhouettes of the flying geese on the right.
The position of the elements is also critical. We unconsciously assume the center of a picture corresponds to a fulcrum. A heavy weight on one side can be balanced by a lighter weight on the other side if the lighter weight is located at a greater distance from the fulcrum.
Another way to achieve balance is through symmetry.
Reflections of the landscape in still water are an example of almost perfect symmetry.
