c1840 Daguerreotype camera by Prof Smetana, Plenz CZ<\/p><\/div>\n

Toronto<\/strong>. The announcement in January, 1839 of the Daguerreotype process electrified the civilized world. First and foremost in improvements were to reduce the time needed to create a ‘likeness’. In 1840 Petzval created a much faster portrait lens to properly expose a Daguerreotype plate in a fraction of the time.<\/p>\n

The 1839 News reached professor Smetana in Plzen, Czechoslovakia and in the following year (1840) he announced his Daguerreotype Camera complete with a Petzval lens made by F. Waibl, Vienna.<\/p>\n

Editor Ev Roseborough describes the historic table top camera used for the issue 16-5 cover shot thusly. “This camera was used in the 1840’s by Josef Frantisek Smetana<\/a>, professor at the Plzen Grammar School, to make daguerreotypes. The camera is mounted on a stand fitted with three adjusting screws.<\/p>\n

“The earliest cameras of this type were simply placed on a table when in use. There is a Petzval lens constructed by F. Waibl<\/a>, a renowned Viennese optician. The plate size is 72 x 81 mm (i.e. 1\/6 Daguerre Standard Plate). There is also a development box where the pictures taken were made visible by means of mercury vapour.<\/p>\n

“Professor Smetana, a cousin of the famous Czech composer Bedrich Smetana<\/a>, was the first scholar in Bohemia to describe Daguerre photography in the Czech language. This description can be found in his book ‘Silozpyt cili fysika<\/em>‘, published in 1842.”<\/p>\n","protected":false},"excerpt":{"rendered":"
