The purpose of this investigation was to study the useful criteria for converting transparencies to reflection prints, and examine the unavoidable departures from the criteria. A single useful criterion was found; that the relative brightness of the reproduction match those of the original. One significant compromise appeared to be in the shadow reproduction in low maximum density reflection prints. It was found that like reflection prints, transparencies do not typically reach relative brightnesses as low as zero. Thus, only a relatively small departure from the 1:1 criterion was likely . Flare in the camera system and viewing conditions limits the maximum density in transparencies to less than sensitometric curves indicate. A simple method for plotting transparency-to-print reproduction was proposed that encorporates the 1:1 relative brightness criterion.
