Symmetry, perhaps the favorite beauty of the Chinese. There is a saying in the old saying: "The beauty of the beautiful, up and down, inside and outside, size, far and near are harmless, so beautiful." Both inside and outside are balanced and appropriate, and the party is "beauty." Symmetry is such beauty.
One of the most significant benefits of thinking about aerial photography is that you can find some beauty that is invisible to normal visual levels. Perhaps the small park that passes through the day has a completely symmetrical mirror image. Believe me, this will be one of the little surprises you want to take and share with more people.
