The classic rules that permit the realization of a solid photographic composition are followed by some very successful photographers like Steve McCurry (see the pictures http://stevemccurry.com/galleries). Here you are:

1. The rule of the thirds – insert the most important elements in the intersection of the two vertical lines with the two horizontal lines.
2. The guide lines – use the lines in the frame to guide the viewer’s gaze.
3. The diagonals – frame the diagonals in order to guide the viewer in the vision of the subject in the well-defined way of the photographer.
4. The frames – use every element such as doors, windows etc. in order to frame the important elements of the scene.
5. The contrast between subject and the background – positioning the subject against a high contrast scene.
6. Fill the photogram – get close to the subject.
7. Dominant eye in the centre – positioning the dominant eye of the subject in the centre of the frame creating more incisiveness.
8. Repeated elements – catch the naturally repeated elements, pleasantly attracted by the viewer’s eyes.
9. Symmetry – frame the subjects in a symmetrical position, to make it enjoyable for the viewer’s eyes.
