The Duchess of Cambridge, nee Kate Middleton, knows her photography - and even professional shutterbugs have taken note! Queen Elizabeth's photographer has even admitted that the 34-year-old is so good behind the lens that she could produce great quality photos on her own.

“I was quite taken aback by her knowledge of photography,” royal lensman Hugo Rittson Thomas told People about his initial encounter with Kate during a 2012 photo session with Prince William. “She asked a lot of technical questions about what I was doing and the set up — she almost caught me out a few times actually.”

Kate’s talents behind the lens have been shared with royal spectators around the world. Earlier this month, Kate marked Princess Charlotte’s first birthday with a series portraits snapped on her very own camera. The doting mom also stepped behind the lens to celebrate Prince George’s birthday, and more famously, the shot of Prince George holding his little sister Charlotte after her birth.

When it comes to the photos of her children taken by Kate, Hugo couldn’t help but admire the royal shutterbug’s work. “I thought they were wonderful pictures,” he said. “Beautifully shot. She captured the joy, happiness and youth of her children which is a wonderful thing and sometimes hard to do as a parent.”

Hugo, who is one of the most respected portrait photographers, is celebrating the release of his new book The Queen’s People. The book features 42 portraits of Queen Elizabeth and other members of the royal household, and has been in the works for the last four years.
