I have just been talking to a long retired draughtsman who worked on the development of new vehicles.
He told me of the works photographer who had a very unusual and ingenious take on the normal ring flash.
He would set a shot up to the point of clicking the shutter, then he would start a high wattage lamp swinging in wide circles above and around the subject; apparently it results in a completely shadow free photograph.
I love lateral thinking.

Yes what i great idea - light painting with a giant bulb.
Did he mention reflections at all?
Now.... Let's see.
At a shutter speed of, say, 1/125th of a second, what radial speed would the lamp need to swing at to get a complete revolution?
Or, conversely, how far away would the lamp need to be to avoid over-exposure at ISO 100 and an aperture of f/22 if a sufficiently slow shutter speed was employed?
