What are the photographic structures?

The law of photographic composition should be based on people's aesthetic characteristics and related theories, using the performance of various layouts to show the content to be reflected through a certain layout.

Photographic composition forms include: vertical rectangle, cross, shadow, triangle, square, horizontal, contrast, diagonal, frame, fullness, rhythm, horizontal, vertical, S-shape, dispersion, center, radial, cross, asymmetry, circle, ellipse, symmetry, well shape and golden section.

Photographic composition always needs to establish the object and expression, and make a second composition when necessary.
