Use gridlines to help you frame your shot.The rule of thirds is perhaps the most popular compositional technique, as it is very easy to master. It involves imagining a nine-section grid over your scene and using the lines to help you position your subject. It
is suggested that you place the main focal point over one of the intersecting points of the grid, as this is where the viewer's eye is likely to be drawn to first. If you are taking a landscape photo, then you can also use the
horizontal lines of the grid to position the horizon in either the top or bottom third. If you're struggling to picture the grid, many cameras have a gridlines display function that you can switch on and use instead.
