Abstract
A method of producing an image comprising impinging a beam of light on first region of a dynamic filter. The dynamic filter comprising at least two regions having different light transmission characteristics. A first region of the dynamic filter transmits a first transmitted portion of the beam of light and reflects a first reflected portion of the beam of light. Impinging at least some of the first reflected portion of the beam of light on a second region of the dynamic filter. The second region of the dynamic filter transmitting a second transmitted portion. The first and second transmitted portions are modulated.
