Symmetry is a compositional technique in photography that is capable of lending a feeling of harmony and balance in a photograph. This technique can be used to capture both natural and manmade subjects that already have a symmetrical structure or can be captured as reflections that show symmetry due to the mirrored image in the frame.
When capturing symmetrical shots either through reflections or a symmetrical structure itself, the photographer needs to observe the scene and find good angles and perspectives that show perfect symmetry while at the same time enhance depth and structure in the image. It is good to experiment with different focal lengths and aperture values to get the desired results. Besides these, light also plays a huge role in how the resulting image turns out.
Here are 19 images, that portray a sense of harmony and balance through symmetry as a compositional technique.
