'But William Henry Jackson and [Carleton] Watkins were all over this country with much bigger cameras. Wet plate cameras. And I believe it was Jackson's series of pictures on the top of Mt. Hoffman, with wet plates, that is, having to take the darkroom, cook the plates on the spot, expose and process them immediately. For the wet plate process you have to complete the development of the image before the emulsion dries. And when the dry plate came in it was a great godsend. I guess we all did the best as we could. If we had very heavy cameras we simply didn't go so far or take so many pictures. Knowing what I know now, any photographer worth his salt could make some beautiful things with pinhole cameras.'
