For those artists that want to master the art of composition, I suggest keeping things simple. If you're going to learn more about Dynamic Symmetry start with the book The Art of Composition: A Simple Application of Dynamic Symmetry by Michel Jacobs. If you're going to explore the 14 line armature of the rectangle, I suggest the book Classical Painting Atelier: A Contemporary Guide to Traditional Studio Practice by Juliette Aristides, my user's guide on The Art of Composition, and the free PDFs by Thomas Kegler found at the bottom of this page.
While there are other educators (along with Myron Barnstone) that suggest the application of overlapping root rectangles to create designs, I no longer recommend this method for artists or photographers. In my professional opinion, I find this approach far too complicated and completely unnecessary for creating a masterful composition. Artists that draw and paint can use straight root rectangles suggested in the book by Michel Jacobs or draw the 14 line armature of the rectangle on any size canvas. Applying design in this manner will give the artist an infinite amount of variety in their lifetime body of work.
Additionally, it's also important to point out that after analyzing many masterworks, I remain somewhat skeptical about the use of overlapping Dynamic Symmetry rectangles to create a composition because this practice is based on the false assumption that every artist uses root rectangles. In truth, many artists throughout history have created designs that employ the use of the 14 line armature of the rectangle as demonstrated in the book “The Painter's Secret Geometry” by Charles Bouleau.
