We propose and implement a method to produce a spatial antibunched field with free-propagating twin beams from spontaneous parametric down-conversion. The method consists in changing the spatial propagation by manipulating the transverse degrees of freedom through reflections of one of the twin beams. Our method uses reflective elements, eliminating losses from absorption by the objects inserted in the beams.
