Shadows cast by lamplight and moonlight create a Hitchcockian atmosphere when rendered in black and white, like these photographs taken over the course of one week. Even scenes of building facades and empty chairs — innocuous and lifeless when pictured in color — glint with the intrigue of classic film noir. All that’s missing is a trench coat-clad detective rounding the corner, his wet footsteps fading into shadow.
