The Principle of Thirds
I like David duChemin’s approach to the so called Rule of Thirds. In his book Within the Frame, he says,”Rules seldom encourage the question ‘Why?’ Principles can’t live without the Why.” That’s the reason I too prefer to call this compositional tool the Principle of Thirds.
When should you use the Principle of Thirds? Whenever using it better expresses your vision for a photograph. It all starts with vision. What do you want to say should always be your starting point. The follow on is – O.K. how am I going to say it?
Take a look at the photograph I took below. I both used and broke the Principle of Thirds in the same shot. What was my vision? My basic starting point was I wanted to photograph the Edmonton skyline. What did I want to say about it? Well, I love the fact that Edmonton is a small big city. It’s big enough to get great concerts, festivals and sports events but has a small enough population and big enough footprint that you have to really go looking for a traffic jam. Whenever I hear Edmontonians complaining about traffic my first question is where else have they lived. I also love the fact that due to it’s population and size, people here really support what’s going on in the community. Unlike bigger cities you won’t have a variety of pro sports games, festivals and conventions to choose from on any given weekend. There will be one major event like the Capital Ex, the Edmonton Indy, Heritage Days, the Fringe Festival or the Folk Fest for example and each event is well supported. Events aren’t in competition with one another.
So for my photograph I had the idea of “small big city” as my starting point. How was I going to say that? I decided to place the skyline low in the frame to symbolize the city’s relative population size and give a lot of weight to the big Alberta blue sky to symbolize the city’s space. Now let’s look at how all that relates to the Principle of Thirds. Obviously placing the skyline near the bottom edge of the frame breaks the Principle as the subject is entirely in the lower third. The Telus building, the tallest in the photograph, is close to the third line but it’s still below. The right edge of that same building, however, is right on the left vertical third line. I liked the way placing that building on the third gave the composition balance and anchored it in a way. So within the one photograph, the Principle is used for effect and broken for effect too. How you use it all depends on what you want to say. What do you want to say next time you look through the viewfinder?
