The
rule of thirds helps the composition of your photographs, making them
easier for the human to understand.
When
taking a photograph, imagine that the image you see is split into a
nine square grid (three rows of three squares). The points at which
the squares intersect are the points of interest and you should aim
to put the subject(s) of your photo at these points.
In
this photograph, I have positioned the little girls face at the
'first' intersection point. The eye instinctively knows to look at
the little girls face even though it is not in the centre of the
photograph.
