The family of angles is the set of lighting angles that produce direct reflection. It is the family of angles that should determine the position we should use for our light sources when lighting any photograph. Any light within the family of angles will produce a direct reflection; any light positioned out of this family of angles will never give off direct reflection for the lenses. The angles in a family of angles are directly related with the focal length of the lens. A long lens will have a smaller set of angles that will give off direct reflection, whereas a short lens will have a very wide angle that will give off direct reflection when lighted within it.

Therefore, the first step of editing a image, before photographing, should be to look at the subject and decide what kind of reflection causes it to appear the way it does; secondly, the photographer should position the light and the camera to make the photograph capitalize on that distinctive type of reflection and minimize the others.
