A couple of mysteries to clear up
The three earliest types of photographs - daguerreotypes, ambrotypes and tintypes - can be difficult to tell apart, but this photo appears to have been developed on to glass rather than metal and therefore is an ambrotype.
Both daguerreotypes and ambrotypes are recorded in New Zealand from the 1850s, the first on a sensitised metal plate and the latter on to glass. They were followed by tintypes in the 1860s-70s using iron plates.
The very distinctive dresses and hairstyles help to support this mid-19th century date. Large, dome-shaped skirts supported by a crinoline and petticoats with a tight waist, rounded shoulders, bell sleeves and central hair parts with sleeked hair to fit perfectly under a bonnet were the fashions of the early Victorian period, 1850s-60s. A date of the late 1850s seems sensible for this photo.

The second photograph appears to come from a later date as it is an albumen print, designed for a photo album. It was donated by L. Bennett and has captured an unknown lady in a studio. Small "carte de visites" were coming into vogue in the 1860s in New Zealand.
Larger ones such as this are known as "cabinet photos". Square corners were popular early on, changing to rounded corners in the 1870s.
Luckily for us the photographer's address and logo can help to further refine the date. Heath & Bullingham had a studio in Plymouth between c 1877 and 1889. This date is again supported by the costume, even further narrowing our date to the 1880s, by the characteristic straighter silhouette.
Crinolines were out of fashion and bustles creating broader hips and backside, with narrow sleeves and simple frills, were in.
With these two photos the elements of fashion could be refined even further because fashions in the Victorian era changed every decade.
![It's your turn. Can you date this photograph (1969 95 682). Photo / Supplied](https://www.nzherald.co.nz/resizer/v2/BVMY6CXBG5ZR5H4BLGXDVPACFY.jpg?auth=dad85af4669367148f4b3e81741890c995aebbf3ad77549ea001c339d49d10af&width=16&height=25&quality=70&smart=true)
Male fashion can be more difficult to date but with the addition of information such as the photographer's details and knowledge of photographic methods used within a particular time frame a more accurate date can be ascertained.
These artefacts are a mine of information even without names and personal stories connected to them.
Now for your turn, can you date the last photo using these methods? Hint: Mr and Mrs Cafler were photographed by Martin & Partington, Auckland, NZ.
