Symmetry & Centred Subjects
These two composition technique are fairly straight forward, but incredible effective. Like with the Rule of Thirds, there are key areas where peoples' eyes are particularly drawn to - the centre of the frame being the most popular. This is one of the most common framing techniques, dating back to the beginning of photography.
By placing the subject in the centre of the frame, it helps the viewers to easily identify the main subject of the frame. When shot at a wide aperture, it allows for an evenly spaced background blur which adds depth to the photo and brings the focus (no pun intended) to the foreground subject.
A symmetrical shot is incredible pleasant to view. It creates a balance in the photo. You can find lots of examples of this in urban architecture photographs or cityscape shots. In the case of the photos with Huntar, and Lotta, the symmetrical background helps to balance out the background and to bring interest to the subject.
