Circular Gestural Photography

During a 1:1 photo sensei workshop, Chris reviewed a selection of my other photos. He observed that they are usually very clear, sharp, often minimalistic. So Chris challenged me to come up with a completely different project and take at least 5 images.
This project is the result. I used a wide angle lens with a ND filter and moved the camera in a circle so the center was more recognizable and the perimeter had more circular structures. It took some experimentation to find the right combination of subject, background, time and movement speed.
