Photographic Composition Rule of Thirds
Perhaps the most well know principle of photographic composition is the ‘Rule of Thirds’.
It’s
one of the first things that budding digital photographers learn about
in classes on photography and rightly so as it is the basis for well
balanced and interesting shots.
Rules are meant to be broken and ignoring this one doesn’t
mean your images are necessarily unbalanced or uninteresting. If you intend to break a rule you should
always learn it first to make sure your breaking of it is all the more
effective!
The basic principle behind the rule of thirds is to
imagine breaking an image down into thirds (both horizontally and
vertically) so that you have 9 parts. As follows.

As
you’re taking an image you would have done this in your mind through
your viewfinder or in the LCD display that you use to frame your shot.
With
this grid in mind you the ‘rule’ now identifies four important parts of
the image that you should consider placing points of interest in as you
frame your image.
Not only this - but it also gives you four ‘lines’ that are also useful positions for elements in your photo.
The
theory is that if you place points of interest in the intersections or
along the lines that your photo becomes more balanced and will enable a
viewer of the image to interact with it more naturally. Studies have
shown that when viewing images that people’s eyes usually go to one of
the intersection points most naturally rather than the centre of the
shot - using the rule of thirds works with this natural way of viewing
an image rather than working against it.

Using the Rule of Thirds comes naturally to some photographers but for
others it takes a little time and practice for it to become second
nature.
In learning how to use the rule (and then to break it) the most important questions to be asking of yourself are:
- What are the points of interest in this shot?
Once again - remember that breaking the rule can result in some
striking shots. Once you understand it you can experiment by purposely
breaking it to see what you discover.
Lastly - keep the rule of thirds in mind as you edit your photos
later on. Post production editing tools today have good tools for
cropping and reframing images so that they fit within the rules.
Experiment with some of your old shots to see what impact it might have
on your photos.
