For twenty-five years, Candace Wark has been a Mechanical and Aerospace engineering professor at Illinois Institute of Technology specializing in the field of aerodynamics and utilizing photography in her research.  Shirley Nannini worked as a high school teacher, coach and administrator at Evanston Township High School for over thirty years and reinvented herself by actively pursuing her passion for photography.  A student wind tunnel project led to a series of steps and turns that evolved into an intriguing art form that neither anticipated and both are enthralled with.  The result has been a resolute artistic endeavor and collaboration formalized in June 2012 as Wind Flow Photography.
