professional photographer, worked at 24 Great Ryrie Street, Geelong, Victoria, in late 1856. Turner’s New Portrait Rooms were at 60 (later 66) Moorabool Street in 1857-67, then at Latrobe Terrace until 1869. In June 1856 Turner lectured at the Geelong Mechanics Institute on 'The Art of Photography’, promoting its superior accuracy to painting. Basing his talk on the quasi-scientific sermons of the Scottish divine Dr Thomas Dick, published as The Practical Astronomer (1855), Turner argued that the minuteness of light particles was a testament to 'the wisdom and beneficence of the creator’.
The photographs Turner showed at the 1857 Geelong Mechanics Institute Exhibition may have been ambrotypes as his surviving ambrotype of three children (National Gallery of Australia) is thought to date from about 1860. At the Melbourne Intercolonial Exhibition in 1866 he showed albumen paper prints of architectural and landscape views in Geelong, including 'large sized photographs of the Chamber of Commerce and the Savings Bank, as well as the United Presbyterian Church, the Mechanics Institute, the Telegraphic and Post offices, the London Chartered Bank, the Town Hall, a well arranged view of Malop Street, and the Private residences of the town’s leading citizens’. Aware of the importance of the photographic portrait to his business, he also exhibited four frames of plain and coloured cartes-de-visite, including portraits of women where 'the pose and the drapery was wonderfully managed’. Cartes of the mayor, alderman, councillors and officials of Geelong were arranged against a crimson background in one frame. His several enlarged portraits included one of Mr Morrison of the Geelong College. He won a medal for his tinted portraits and another for his architectural and landscape views.
Reviewing the photographic views at the exhibition in the Australian Monthly Magazine , 'Sol’ commended Turner’s method of printing and presentation. 'Vignetting portraits has long been a favourable occupation’, he noted, 'and we have sometimes seen it applied to landscapes, but never in this particular way, and we certainly admire the exquisite finish it gives to the picture’. The Geelong press, on the other hand, admired Turner’s 'business enterprise’ in using these views and portraits for local publicity when he set up 'a miniature exhibition’ in his New Portrait Rooms before sending the photographs to the Melbourne Intercolonial Exhibition, particularly as he advertised it at precisely the time that J. Norton and L. Ormerod 's commissioned views were on display in the Geelong Town Hall.
His ability to make the most of an opportunity again surfaced the following year, on the occasion of the visit of the Duke of Edinburgh to Geelong. A pair of plates he took, showing the reception for the royal visitor on the Yarra Street wharf with the mayor welcoming the Duke and the town clerk reading the corporation’s address to his Royal Highness, appeared as engravings in the Illustrated London News soon afterwards.
On 9 October 1869 a large fire in Geelong destroyed five buildings in Moorabool Street, including Turner’s premises, and he disappeared from Geelong. Newton notes that Joseph Turner, described as 'an excellent photographer’, was appointed to the Melbourne Observatory on 10 February 1873 and remained there until 1883. Lunar photographs by Turner are held at the Mount Stromlo and Siding Springs Observatory (Australian Capital Territory) and at the Australian National Gallery. Other photographs are in the La Trobe Library and at Melbourne University.
