<p>A lighting system and method with variable light intensity for use in motion picture photography. In the lighting apparatus, light emitted from a source (18) is passed through an aperture (36a) and then through a section of a movable, neutral density filter (50). The preferred filter (50) is specifically designed to have a variable density, continuously increasing from one side of the filter to the other. By changing the position of the filter (50), selectively placing higher or lower density sections in the light path, the intensity of the light emitted by the lighting apparatus may be varied. The neutral density filter (50) is selected to be generally color neutral so that the color quality of the light passing therethrough remains unchanged.</p> |
