In the photo, William and Kate pose against a simple backdrop with their three children, Prince George, 10, Princess Charlotte, eight, and Prince Louis, five, in matching white shirts and jeans or black pants (or shorts in Louis' case).
David and Sylvia thought the photo gave a "stopped back 90s vibe". They spoke to Camilla Tominey, associate editor at The Telegraph in the UK, about Kate and William's photo and King Charles and Queen Camilla's photo, which was "very different".
"A little bit different, wasn't it?" Camilla said of Kate and William's photo, adding, "A kind of monochrome monarchy, I don't know if it was particularly Christmassy, but it did provide a kind of image of unity, particularly for the Prince and Princess of Wales after everything that's been said and done in recent weeks after Omid Scobie's second book about Harry and Meghan."
Speaking about the King and Queen's card, Camilla added it was "more traditional" as it featured a photo of them at their coronation.
"But I suppose this is the palace's way of very quietly and subtly insisting to the world that everything is business as usual as is the epitome of the tea towel slogan guys, they keep calm and they carry on!" she said.
David questioned why she thought William and Kate chose to go for their black and white "back to basics" look, with Camilla responding, "I don't know, I mean, I would have quite liked to have seen them in Christmas jumpers or something, but having said that, you guys know how hard it is – and anyone watching this knows how hard it is – to get all three children looking at the camera, smiling and seeming happy."
"Josh Shinner is the guy who took the photos – he's taken photographs in the past of celebrities and more kind of fashion and edgy entertainment type images. So maybe they're just trying to seem a bit more cutting edge, but it was not particularly Christmassy."
David added that the photo looked like it was "taken at a mall", adding, "They could have made more of an effort."
Sylvia agreed, saying, "It is, it's the baby photos in the shopping mall kind of vibe."
She also questioned Camilla if she thought the royals would ever make a statement about the allegations against King Charles and Princess Kate that appeared in the Dutch translation of Omid Scobie's latest book Endgame, with the associate editor saying she wouldn't expect anything of the sort.
"I think the policy that the late Queen adopted of never complain, never explain has served the royals quite well in the face of all this," Camilla responded. "I mean, Omid Scobie's tied himself into all sorts of knots over how those two names ended up in the Dutch translation.
"Initially, he said it was lost in translation, then seemed to have found it in translation. Clearly, it must have been in the original for it to have ended up in the Dutch copy. So that's all been a little bit of a hullabaloo, and I think with this image and, indeed actually, the family turning up for that carol concert that they starred in last week – this is just them saying we're going to rise above and that's probably the best policy.
"At the end of the day, they don't have the option of doing a sit-down interview with Oprah Winfrey. And would we really want them to? Historically when royals have sort of done interviews and overshared, if we think about Diana and the panorama interview, or even when Prince Charles spoke to [Jonathan] Dimbleby, I think they live to regret it."
