Principles of Visual Dynamics
If you like rules, remember exceptions prove the rules. Being too insistent on the application of hard and fast rules can blind you to many exceptional opportunities. If you don’t like rules, remember that while there are no absolutes there are forces at work that have consistent tendencies. Denying or ignoring universal principles will lead to unpredictable unrepeatable results; you’ll achieve success far less frequently and be far less able to repeat your successes.
Forget rules. Forget absolutes. Forget musts. Instead develop an awareness of visual principles. Look for the unique power each element has to influence a composition. Develop a sensitivity to how elements and combination of elements make the forces at work in a composition stronger or weaker. Instead of composing formulaically, you’ll then be able to improvise. Understanding the principles of visual dynamics will help make your decision making process more informed, it will not make choices for you. Awareness is the key. Better awareness brings better choices bringing better results.
