"Yellow Movies" was a project of Conrad's in 1973 of twenty "movies" consisting of rectangular borders painted in black house paint on large pieces of photographic paper, effectively framing each sizable expanse of emulsion. Conrad's concept came from a continued attempt at pushing the framework of film, and his interest in engaging the audience in long spaces of time. He wanted to make a film that would last fifty years, but knew that "normal materials" and projection could not last that long. So he created an entirely new conceptual stratagem for "Yellow Movies" whereby the physical aging and transformation of the emulsion itself would constitute a definitively slow-motion moving picture over such an extended period of time.
