ABSTRACT:
A day-night picture achieves a realistic reproduction of the twinkling of distant city lights or the like, by backlighting small apertures in the picture with a fine, randomly moving reflection pattern obtained by suspending pieces of crumpled reflective foil from fine threads behind the picture above a light source whose heat creates convection currents which slowly move the foil pieces in a random manner.
