In the world of photography, there are certainly plenty of ‘odds’ but the ‘rule of odds’ is something different entirely. The rule suggests that an image is more visually appealing if there are an odd number of subjects. The theory proposes that an even number of elements in a scene is distracting as the viewer is not sure which one to focus his or her attention on. An odd number of elements is seen as more natural and easier on the eye. To be honest, I think there are plenty of cases where this is not the case but it is certainly applicable in certain situations. What if you have four children? How do you decide which one to leave out of the shot? Personally, I’d go by future earning potential.
