But despite the impeccable lighting and skilled focus of the shot, the portrait wasn't commissioned by a top photographer.
In fact, most of the photographs of the family released to the world media have been taken by Kate herself – a talent that clearly runs in the family, as the first ever official photograph of Prince George in 2013 was taken by her very own father, Michael Middleton, at their family home in Berkshire.
And though at more formal engagements professional photographers have been employed (most notably Mario Testino, who's worked for the family several times) an expert has revealed the real reason why Kate takes her own snaps.
Gina Jones from Bumpkins, The Baby Show's lead experts in baby photography, told MailOnline: 'It shows how modern Kate and William are by being more accessible and having a hands on approach. It also shows that they are resourceful with money as you often see Kate in high street fashion and sometimes repeating outfits, and so by taking her own photos this again shows how she is savvy with money.'
Kate has been universally acknowledged for her photography talents by art critics and fans alike, and earlier this year received an honorary lifetime membership to the prestigious Royal Photographic Society.
In a Facebook statement released at the time, RPS said of her work: 'A keen and skilled photographer who has taken official portraits of her children Prince George and Princess Charlotte, The Duchess is the latest in a line of royals to become associated with the RPS, an educational charity dedicated to promoting photography and supporting photographers.'
'Queen Victoria and Prince Albert were early patrons of the RPS, and Queen Victoria granted the Society use of the title 'Royal' in 18914. The Duchess joins other official royal photographers who are RPS members, including Josh Olins, Matt Porteous and Christopher Jackson.'
