Lady Clementina died quite young from pneumonia and it has been suggested that her constant contact with the chemicals needed for photography may have weakened her immune system. Being mother to ten children as well probably didn't help.
The largest collection of her photographs are at the Victoria & Albert Museum and include general outdoor scenes as well as stylized family studies. The stables at Dundrum House appear to have been a favourite setting.
Below is a portrait of Henry Brougham Loch and one of Clementina's daughters, Isabella. He went on to a varied life as an eminent colonial administrator, serving as Governor of Victoria and High Commissioner for South Africa. The entry for this photograph in the V&A collection reads:
"Hawarden used the balcony on the south side of her house in Princes Gardens in London as an open-air studio, floating in space. She posed her daughter Isabella Grace beside her mother’s cousin, Henry Brougham Loch. This double portrait must date from the summer of 1861, because the houses on the south side of the square are still being built. Virginia Dodier has written that Loch was a celebrity in 1861, because he ‘survived imprisonment by the Chinese during the Second Opium War’."
Not sure what this next study is about - prayer? - but typical of many in the recognisable style of Lady Clementina Hawarden.
