>From the time readily manufactured silver gelatin emulsions were factory
manufactured, any means of photography was an 'alternative.' Does that
settle the question?
Historically speaking, it was a paper manufactured by Defender that was
considered the first factory made 'silver gelatin' paper. Although, the
Chicago Albumen Works made 'aternatives' to that, and I'm not sure when the
distinction became known to favor silver gelatin.
