Does anyone have instructions in 25 words or less on how to make a Daguerreotype? I was thinking that possibly copper clad board used for printed circuit making might be a suitable start. I wonder how much mercury it takes as I have just acquired on the black market several mercury thyratron tubes. Each contains about 20 thermometer amounts of Hg. I also have a couple of what are called Farrand lenses - f/.7 at 75 mm focal length. So where do I start? - sure I could look it up on the net but then we would have nothing to talk about here!! Andy BTW, Cunningham, Palcewski and Mitchell - hint!
