In the Daguerreotype days there was a "portrait factory" on Broadway, where likenesses were turned out as fast as coining, for the small charge of twenty-five cents a head. The arrangements for such rapid work were very complete. I had a dollar's worth of these "factory" portraits. At the desk I paid my money, and received four tickets, which entitled me to as many sittings when my turn came. I was shown into a waiting room crowded with people. The customers were seated on forms placed round the room, sidling their way to the entrance of the operating room, and answering the cry of "the next" in much the same manner that people do at our public baths. I being "the next," at last went into the operating room, where I found the operator stationed at the camera, which he never left all day long, except occasionally to adjust a stupid sitter. He told the next to "Sit down" and "Look thar," focussed, and, putting his hand into a hole in the wall which communicated with the "coating room," he found a dark slide ready filled with a sensitised plate, and putting it into the camera, "exposed," and saying "That will dew," took the dark slide out of the camera, and shoved it through another hole in the wall communicating with the mercury or developing room. This was repeated as many times as I wanted sittings, which he knew by the number of tickets I had given to a boy in the room, whose duty it was to look out for "the next," and collect the tickets. The operator had nothing to do with the preparation of the plates, developing, fixing, or finishing of the picture. He was responsible only for the "pose" and "time," the "developer," checking and correcting the latter occasionally by crying out "Short" or "Long" as the case might be. Having had my number of "sittings," I was requested to leave the operating room by another door which opened into a passage that led me to the "delivery desk," where, in a few minutes, I got all my four portraits fitted up in "matt, glass, and preserver,"--the pictures having been passed from the developing room to the "gilding" room, thence to the "fitting room" and the "delivery desk," where I received them. Thus they were all finished and carried away without the camera operator ever having seen them. Three of the four portraits were as fine Daguerreotypes as could be produced anywhere. Ambrotypes, or "Daguerreotypes on glass" as some called them, were afterwards produced in much the same manufacturing manner.
