<p>A scanning light source system for projecting onto each area of a complete painting or other planar subject (120) a beam of light and for moving said beam vertically and horizontally. The vertical movements comprise a succession of sweeps across the painting for the purpose of consecutively illuminating each part of the painting sufficiently strongly so that the whole may be photographically reproduced more satisfactorily than has been possible heretofore, e.g., through the use in combination of Kodak No. 6121 duplicating film or another gamma 1.0 film, polarizing filters, and a lens aperture of f22 or smaller. The horizontal movements take place on horizontal rails (20, 21) and position the light source (2) for each vertical sweep. The vertical movements, controlled by motor (70), position a frame, which includes rails (20, 21), light source (2) and reflector (5), on uprights (125).</p> |
