I have some friends who practice naginata, and were gracious enough to let me join one of their sessions with my camera.
I used the new 210mm lens on the Crown Graphic and loaded the holders with green sensitive X-Ray film. I am nearing the end of my first box of that.
There were two great obstacles, one was the (lack of) speed of the film coupled with the poorly lit interior of the gym. The other was that I used the camera as a view camera, and they moved about quite a bit.
