'Cartes de Visites' - Using Hairstyles to date photographs...
Recently I noticed some quite distinctive elements in two photos when I was trying to confirm the identities of two women in my Grandma Hooper's old album; one of whom I suspected to be my maternal great grandfather's older sister.
I came across the following article. It sits nicely with the ideas and resources already shared by Wendy Sturgess on costuming, but has a little more about hairstyles. It's an enjoyable read and from a reputable source (NGV). It suggests it may have been taken in the 1870's - it was taken in England, but apparently 'fashions' did not take long to reach Australia.
Here's a link to a recently published article on Cartes de visites.... and Melbourne photography studios https://artblart.com/2022/01/16/photographs-australian-cartes-de-visite-melbourne-1860s-1880s/
