The rules of composition are there to make good images great
RULE OF THIRDS
Divide your image into three equal sections, horizontally and vertically. The strongest points for placing your subject are at the intersections of four imaginary lines. Positioning the landscape’s horizon on one of the horizontal lines will also strengthen your composition.
GOLDEN RATIO
This souped-up version of the Rule of Thirds uses the golden ratio to position your main subject. Placing a subject in the smallest curl of the Fibonacci spiral (worked out using the golden ratio of 1.618) will draw the eye through the image towards it. The maths is complicated but fortunately all you need to do is familiarise yourself with the shape of the spiral and use it when framing and placing your centre of interest.
GOLDEN TRIANGLE
This variation is very useful when there are naturally occurring diagonal lines in your scene. This rule states that when you draw a line from one corner to the opposite corner of your frame, and then draw a perpendicular line from any open corner to the first line that intersects it at 90 degrees, you find a strong position for your subject. Any naturally occurring lines running through the image should be placed on or close to the first diagonal line.
