Photography technique – flame & steel
-
Folks,
Can you help out my memory? A few months back there was a documentary on the BBC about photography through the ages featuring various photographers. One very early technique that was shown was photography on a steel plate. The plate was highly polished and the image exposed, then sealed with a flame. The result was similar to an image on a mirror. I’ve been trying to find the technique on the web but to no avail. Does anyone have a copy of this documentary that could look back to see what it was? It’s wrecking my head!! :(

yes it was the series Genius of photography, a BBC production and it is a great series, it seems hard to get on dvd though (or else I’m looking in the wrong places)
Louis-Jacques-Mandé Daguerre invented the ‘Daguerreotype’ in 1839. It was a polished silver coated copper plate exposed in darkness to iodine to create a coating of light sensitive silver iodide. the plate was exposed to light in the camera giving a latent image on the plate, this image was then developed by mecury vapour and then fixed with with a warm solution of ordinary salt. These images were high in detail and were reffered to as ‘mirror of nature’ by Daguerre himself.
Search Daguerre on the net there is loads about him, also you might be interested in Henry Fox Talbot who developed another technique at the same time and a rivalry developed to see which had the better product.
