Recessed fixtures with carefully selected bulbs that optimize overage of the artwork or pathways without spilling light into the adjacent areas are crucial to create a layered effect. Although it is somewhat difficult to capture the true elegance with photography, you can see where the lighting highlights artwork or architectural features. The lights down the center of the hall light the floor and rug, not the walls. This allows the light on the artwork to be carefully calibrated to bright out the artists intent. There is really only a single dimming position that allows the art to really explode off the wall. Beam spread, color temperature and intensity all combine to make the homeowner say "Wow, I've never seen my art like this before".
