Warren T. Thompson (photographer)

From Wikipedia, the free encyclopedia

Warren T. Thompson (active 1840 - 1870) was an American photographer. Between 1840 and 1846 he worked in Philadelphia. He also worked in Paris.

In 1843 Thompson refined Daniel Davis Jr.'s electroplating method for colouring daguerreotypes by using a gum tragacanth resist. With this technique colours could be built up in the manner of some types of printmaking.
