Camilla commissioned her stepdaughter-in-law to photograph her and gave an insight into their friendship, saying: "She did really good pictures and you know she does it very naturally… we had a lot of fun doing it.
"It was very relaxed and of course very kind of the Duchess of Cambridge… she's an extremely good photographer and it was all very casual, there wasn't much hair and make-up – it was just done in the garden with a lot of laughs – it was a lovely way of doing it."
