What has the shell of a Nautilus, mathematics and a great photographic composition got in common? The answer is surprisingly simple: Fibonacci’s ratio. If you answered Golden Mean, Phi, or Divine Proportion, then you would have been equally correct. Since the days of antiquity, this ratio of 1:1.618 has been used to create everything from great art and architecture, right through to today’s wide screen televisions. In fact, anything that you find aesthetically pleasing, be it natural or man-made, will more than likely be based on this simple rule of harmonious proportions. When these proportions are applied to photographic composition – they carry the title ‘Rule of Thirds’. Most people, when they are composing a picture in a frame, naturally place the subject in the centre of the viewfinder. Nothing wrong with that – but it does tend to produce images that are flat and uninteresting. This is where the ‘Rule of Thirds’ can be very useful – it encourages you to place the subject of your photo in or around the four intersections of the on-screen grid (see image above) – be it a tree, house, face, eye, etc. – the list is as endless as the subject matter you are framing. It’s a very simple way to to apply ‘Fibonacci’s Ratio’ and therefore making your photos more intriguing and aesthetically pleasing. It’s not a hard and fast rule, by any means, but it can be a very useful tool when composing your pictures. I encourage you to continue to research this fascinating principle online – it has occupied and delighted great minds in the arts and sciences for centuries.
