Dear Sirs, I am a new member of this list. I'm a Spanish photographer based in Barcelona. I am intending to process some ancient plates exposed perhaps in the first years of 20th century. Those are stereoscopic plates which came in three magasins, together with a French camera made in the first years of that century. There is no information neither about the emulsion, neither about when they were exposed. I can only presume it is orthochromatic negative, which allows to process under red light. I can also presume this three magasins haven't been preserved in the best conditions.I would like to contact somebody familiar in this subject, who may help me in this process. Since I only have three plates, I can't do too many tests. I would really thank anybody to help me.
