Prince George's New Instagrammy Photos

Camera Press/Redux

Proving they really are the ne plus ultra of modern princes and princesses, William and Kate have released a curiously Instagram-influenced picture of Prince George for his second official photo.

"The photographer's given it an Instagram treatment it seems," opines one photographer of the Royalist's acquaintance. "The blacks have a lot of blue in them and the highlights are yellow. Classic filter stuff."

The informal snap, shot as the couple peer through a window at Kensinton Palace with Lupo and George, was released today. The photo will provide much needed imagery for journalists over the next few weeks in advance of the royal tour of Australia.

Other than a glimpse of the curtains, little of the Cambridges' renovated Kensington Palace home can be seen in the photograph.

It is the first official picture of Prince George to be released since his christening last October.

The visit to Australia and New Zealand will be his first official overseas tour. The trip echoes the Prince and Princess of Wales's visit to Australia and New Zealand in 1983 when the couple took William, then aged nine months, with them.
