When non-photography folks take photos with their phone or camera they will generally place their subject right in the middle of the frame. As we learn about composition we quickly learn that centering a photo is not always pleasing to the eye.
However, there are times when centering a photo is actually a good compositional technique. When you want to make your subject dominant and draw attention to it, centering is a good way to do so. Centering allows the viewers eye to settle on the subject. In the photo above I placed the golf ball and the tee directly in the centre of the frame. Centering makes it dominant in the photo while also creating scale. Another time where centering works is when you want to create symmetry in your photo.
As you look at taking your photo today, consider how centering your subject can enhance its composition.
