For those photographers interested in composite photography (cutting and pasting multiple images together to create a composition) applying Dynamic Symmetry is used in the same manner as the artist that draws and paints. In other words, the composite photographer is not limited by the amount of time for creating their final design.
Also, it's important to point out that composite photography and the application of Dynamic Symmetry should not be restricted to one design scheme - meaning the use of camera grids becomes even less relevant. Much like the artist, the composite photographer will use the angles of their subject to dictate the rectangle they choose for their design and also have the ability to move individual elements around the frame as they see fit.
For those interested in learning more about masterful composite photography, I recommend studying Brooke Shaden’s work.
