Catherine, Princess of Wales, has long been admired for her calm poise and understated elegance — especially in public appearances. But behind her polished demeanor lies a simple rule that guides how she interacts with the press, a principle reportedly passed down from Queen Elizabeth II and Prince Philip.

It’s not about style or posture. It’s about intention.

A lesson passed from Prince Philip to future queens

Prince Philip, who spent more than seven decades beside Queen Elizabeth as consort, understood the intense scrutiny that came with royal life. Having married into the monarchy himself, he was known to quietly offer advice to newer members of the family — especially those navigating the pressures of sudden public life.

One of the people he is said to have influenced is Catherine, who will one day become queen. According to royal biographer Gyles Brandreth, Prince Philip shared with her a simple but powerful rule: never look at the camera.

Prince Philip once explained it like this:

“If you believe the attention is for you personally, you’re going to end up in trouble. The attention is for your role, what you do, what you’re supporting. It isn’t for you as an individual. You are not a celebrity. You are representing the royal family. That’s all.”

By following this advice, Catherine stays grounded in her role, even under the weight of global attention. Brandreth recalled joining her during a public walkabout and noting that she never looked at the camera — always at the people.

Respect for the role, not the fame

Prince Philip was reportedly cautious about how fame could affect individuals within the royal family. Though he had reservations about the attention that surrounded them, he was relieved by Catherine’s approach. According to Brandreth, he saw her as “level-headed” and genuinely focused on duty over image.

This mindset wasn’t reserved just for Catherine. Philip also tried to support Princess Diana as she adjusted to the expectations of royal life. Royal author Ingrid Seward wrote that Diana, early in her marriage, was often seated next to Philip at formal dinners — and he made a point to look after her. He knew the strain such occasions could place on someone new to the institution.

Meghan Markle has also previously shared that Prince Philip was warm and welcoming when she first joined the family.
