Getty Images royal photographer Chris Jackson previously told Insider that the Highland Games in Scotland are one of his favorite royal engagements because "it's a lovely opportunity to photograph the royal family at an event where they're quite relaxed."
"Often, you look at the Queen and the Prince of Wales, and you almost forget that they're mother and son," Jackson said. "So to see them at an event like this, clearly enjoying themselves and feeling relaxed, it reminds me of these family bonds and this relationship."
