| Zusammenfassung: | A lens filter assembly comprises a plano-convex lens 1 adapted so that the convex surface thereof defines a focal plane substantially coincident with the plane surface thereof and a filter storage medium 5 located adjacent said plane surface. The filter storage medium may be a spatial light modulator secured to said plane surface, a removable substrate element bearing a photographic emulsion, or photographic emulsion coated on said plane surface. |
