I use a Roundshot rotating camera...on the slow speed a full 360 rotation takes about 3 minutes.... I took some photos of a dancer and she was in one of the photos about 15 times !! If you keep still in front of the camera as it`s rotating you appear sharp.... if you move slowly you are blurred and if you move past the lens quickly you are not recorded at all. It`s great fun to use for this sort of picture and the possibilities are many.
