Ambrotypes typically have a dark background, and daguerreotypes typically reflect light from the metal on which the image is fixed, rendering these two types of photographs difficult to view in natural light; the former is often too dark and the latter too bright and mirror-like. They are even more difficult to appreciate in a gallery context which might maintain adherence to industry-standard lighting but which ignores the very special requirements of lighting, placement on walls or in cabinets behind glass, and distance at which the spectator is kept from these two types of early photographs. The National Gallery has made no effort to overcome these long-standing problems in this exhibition, resulting in a less than happy visitor experience.

The carte-de-visite portraits below by Thomas J. Nevin of himself with stereoscope (1865), his fiancee Elizabeth Rachel Day (1865), and of his wedding day with his bride Elizabeth Rachel (1871) were not in the exhibition, but one photograph on display has a connection with Nevin.
Titled "Married Couple with Dog" it features the carpet which Nevin had acquired from Alfred Bock by 1867, along with their studio and glass house at the City Photographic Establishment, 140 Elizabeth St. Hobart. The same carpet can be seen (below, right) in the solo portrait of Nevin's fiancee Elizabeth Rachel Day, taken ca. 1865. Nevin began an apprenticeship with Bock in early 1863 and succeeded to the business on Alfred Bock's sudden departure (due to insolvency) to Victoria in 1867.
The question then arises as to the attribution of the item titled "Married Couple with Dog". Further questions arise around the information provided by the NPG exhibition about this Alfred Bock photograph (borrowed from the NGA Collection). The accompanying commentary on a white card placed next to the photograph asserts that Alfred Bock's father Thomas Bock was a daguerreotypist, but in The Mercury on 22 May 1900 Alfred Bock claimed that his father never took a photograph in his life. The photograph in question is indicated in this TV snapshot (from the ABC news item) below:

The photograph indicated on the wall is the one attributed to Alfred Bock in which the couple are seated on Nevin's carpet. It is the same carpet on which he photographed his bride-to-be, Elizabeth Rachel Day, ca. 1865 (below right):
