Well, i agree that this cannot show the true deflection of the shinai 100% without a very fast shutter speed. However, from the the kind of blur seen in this shot, the curvature of the shinai is depicted suprisingly accurately. If this were a 'trick' due to a slow shutter speed, the blur would be somewhat different.Originally posted by Charlie Kondek
Yes, it's a trick of the camera, I think. Either that or he's using a very big banana to attack him.
