(1) The rule of thirds states that the ratio of the length of the
smaller part of a line to the larger part of that line equals the ratio of the
larger part of the whole line.
This ratio of 2:3 is used to locate the
is 2/3 of the picture width from either side and 2/3 the picture height from

Using ratio of 2:3 to place center of interest
scene. This creates a hypnotic effect on the viewer. The viewer's eye goes

picture and might move his attention away from the picture completely.
