VERY interesting! I have never heard of this process although I was aware
that there were claims for a color daguerreotype process that some thing is
a sham. One could easilly have some copper plates made. The only problem
might be in obtaining hydrogen sulfide. As I recal sulfuric acid on copper
produces this gas. Does anyone know for sure? Perhaps that would not be the
best way to produce it. Does anyone have any additional info about this

Thanks Jeff and best wishes,

&gt;From the back of an old Daguerreotype manual:
&gt;COLORED DAGUERREOTYPES ON COPPER.--To effect this, take a polished plate
&gt;copper and expose it to the vapor of iodine, or bromine, or the two
&gt;substances combined; or either of them in combination with chlorine.
&gt;gives a sensitive coating to the surface of the plate, which may then be
&gt;submitted to the action of light in the camera. After remaining a
&gt;time in the camera, the plate is taken out and exposed to the vapor of
&gt;sulphuretted hydrogen. This vapor produces various colors on the plate,
&gt;according to the intensity with which the light has acted on the
&gt;parts; consequently a colored photographic picture is obtained. No
&gt;process is necessary as exposure to light does not effect the picture.
&gt;By this process we have an advantage over the silvered plate, both in
&gt;economy, and in the production of the picture in colors.
&gt;Anyone give it a go? What colors, exactly? Doesn't sound like the color
&gt;process that someone else was trying to perfect at the time, and it most
&gt;CERTAINLY isn't the Polaroid answer to the color problem.
&gt;It _is_ interesting, though.
