I rarely use camera grids to compose my photographs, and I never use them when I'm shooting professional work. For landscape photos, I occasionally use the basic armature of the rectangle. However, because Dynamic Symmetry allows the artist to create an infinite number of compositions, I'm careful not to restrict creativity by locking my images into one design scheme. Artists and photographers that continually use the Rule of Thirds grid are faced with this problem.
While some online marketers claim camera grids are necessary for applying Dynamic Symmetry to a photograph these educators lack real-world experience, misinterpret the application of Dynamic Symmetry in photography, are trying to increase camera grid sales, and overlook the important fact that tools should benefit the artist, not restrict their artistic freedom. Camera grids are not only unnecessary but if overused a photographer's visual literacy skills become stunted, and their images predictable and overly mechanical.
In my combined 36 years experience as a photographer, educator of design, and graphic artist I have yet to come across any highly skilled, historically relevant photographer that used camera grids to compose their images and for any professional to engage in such a practice would mean a loss of credibility. For the photographer that is taking their first steps towards learning more about the art of composition, it should be fully understood that camera grids are only used as an aid for the beginner student - not a tool for the skilled professional.
