I was in salt lake city and visited this store in the mountains it was filled with photos taken from a Daguerreotype camera. (I think that's what it is called) anyway the photos are incredible! And they use silver plated copper plates. Its an OLD camera but I was told that it is actually better than any moften camera. When you dim the lights the photos will actually dim in the same manner as if you were there. Of coarse they wanted on average 40-50,000 dollars for one photo. Has anyone ever used one of these cameras? Would be kind of nice to hear about it.
