Whenever a photographer asks me if camera grids are necessary for applying Dynamic Symmetry to a photograph, my first thought is "ugh,..here we go again. They must have seen another advertisement on YouTube." Of course, I don't say this out loud or respond in that manner. Instead, I simply bite my tongue and reply, "skilled photographers don't need camera grids to take masterful images and haven't since the early days of photography."
If you're a photographer new to Dynamic Symmetry and are thoroughly convinced that plastic Dynamic Symmetry grids are needed to create great photographs, you're not in touch with what it means to be a trained artist nor are you familiar with the history of photography. The fact is, regardless of the medium used, a high skilled artist is one that acknowledges that there are no shortcuts when it comes to understanding design and creating a masterful body of work requires years of training and dedication that very few artists and photographers have these days.
However, for those gadgeteers that are overly fixated on using camera design grids and need "proof" that highly skilled photographers don't require them, I recommend analyzing art. By taking the time to study masterworks and solid design principles, what you will discover is that most (if not all) of the celebrated photographers throughout history have employed elements of Dynamic Symmetry in their photographs without ever using gadgets, gizmos, or plastic grids taped to their viewfinder.
"Musicians don't constantly stare at their fingers while playing an instrument any more than a master photographer will look through a design grid before taking a picture." - Dynamic Symmetry Art.
