Abstract A process for making a metal-glossy image which comprises treating a silver halide image with a solution containing physical developing nuclei and then treating the silver halide image thus treated with a solution containing a solvent for silver halide. A projection process which comprises treating a silver halide image with a solution containing a solvent for silver halide to provide a metal-glossy image, applying to the surface of the metal-glossy image an illuminating light beam for transmission and an illuminating light beam for reflection, combining the penetrating light beam and the reflected light beam, and projecting on a screen the combined light beam to provide a projected image having various contrasts.
