Leading lines refers to a technique of composition where the viewer of your photos attention is drawn to lines that lead to the main subject of the image. A leading line paves an easy path for the eye to follow through different elements of a photo.
Symmetry
An object has reflectional symmetry line or mirrorsymmetry if there is a line going through it which divides it into two pieces which are mirror images of each other. An object has rotational symmetry if the object can be rotated about a fixed point without changing the overall shape.
Pattern
Pattern photography utilises elements that are repeated. The repetition of lines, shapes, tones or colour can create interesting images. There arephotographerswho use thepatternas the main subject of an image while others use it to enhance the overall composition and look of thephotograph.
