Although the sitter in the portrait is currently unidentified the museum recognises the importance of maintaining its collection of daguerreotypes as examples of the fashion and early photographic processes from the period. This photograph was purchased by the museum in 1961 and although the beautifully painted sky backdrop suggests it was done by a photographer of high repute we are still unable to categorically state whether it was taken in Australia or not. It is hoped that research may at some future date identify the sitter in this photograph and H6866 purchased at the same time.

This photograph is significant because it is one of the few surviving daguerreotypes which may have links to Australia. While millions of daguerreotypes were produced around the world and many thousands in Australia remarkably few have survived that can be linked to Australian society during the 1850s and 1860s. The first daguerreotype was taken in Australia in 1841 and its first professional photographer George Baron Goodman arrived in 1842. However very few photographs from the 1840s have survived and most extant examples were taken between 1850 and 1865 or are come from overseas.

In 1839, the first photographic process, the daguerreotype, was unveiled by the Frenchmen Louis Daguerre who had invented it with the assistance of Joseph Niépce. Daguerreotypes became an overnight sensation and were immensely popular even though they were expensive and could only produce one unique positive print.

Daguerre died in 1851 and in this same year a new photographic process on glass, the ambrotype was introduced. Ambrotypes were both cheaper, and could be viewed more easily than the silver surface of the daguerreotype, and eventually replaced the earlier process in popularity. Although still in demand from conservative customers, and those who appreciated their high level of the detail, daguerreotype had essentially disappeared by the early 1860s.

The daguerreotype was a remarkably complex process. To make a daguerreotype you firstly had to clean a piece of silver plate to a mirror finish using a slurry made from pumice in oil, then give it a number of washings in nitric acid and water to remove the oil residue. Secondly the prepared plate had to be sensitised by exposing it to iodine vapour. Then the sensitised plate was placed in a camera and exposed to light, the exposure time varied according to the time of the day, the season of the year and the weather, and could be from three to thirty minutes. The silver plate was then exposed over heated mercury vapour until an image appeared and lastly it was fixed by placing the plate in a hot solution of common salt or a solution of sodium thiosulfate.

Keeping a supply of the correct chemicals, making sure the plates and workspace were kept free of dust and ensuring there was a supply of clean water all conspired to limit the practicality of travelling with a camera. This coupled with the lengthy exposure times, which were a result of deficiencies of these early photographic emulsions and the quality of the camera's lens, made the whole process complicated and unwieldy.

Photographic positive, daguerreotype, studio portrait of unidentified woman seated with books, silver / copper / glass / leather / wood, photographer unknown, Australia, 1849-1859

A daguerreotype showing a 3/4 view of a woman photographed seated in a studio setting. The woman wears dark coloured dress with a white lace collar and has her hair in ringlets. She sits in a straight backed chair and rests her left elbow on the table beside her. Two books can be seen on sitting on the table.The daguerreotype is enclosed in a hinged case made from wood that has been covered in leather. The case opens to reveal the daguerreotype on the right hand side. The daguerreotype is framed in an arch shaped brass mat. A glass panel sits over the top of the brass mat. The opposite side of the case is lined with black velvet. Two metal clasps on the side of the case allow it to be closed securely. The daguerrotype is stored in custom-made enclosure with a support.
