Re: Rotating Pinhole

to do that you would need a shutter. without one the picture would be a blur. this is how a zoetrope works and how people see moving images (suspension of disbeleif). i made a 16mm film camera this way, and in an early attempt, i tried to bypass the shutter and ended up with no real image. the shutter really only has to stop the film long enough to record an image. it could even be just your hand. this method however, produces multiple pictures. if what you are going for is a panoramic type thing (one picture), you would probably be better off with multiple pinholes...
