Posture can also make a significant difference. Diana may be standing differently from Charles, while uneven ground at Balmoral could affect their apparent heights. Footwear, the position of their feet, and the angle of the camera can all contribute to the illusion.
The photograph also needs to be considered alongside other pictures from the same period. Diana and Charles were photographed constantly, and their relative height appears different depending on the setting, camera position, and how they were standing. A single frame cannot establish that something unusual was deliberately being hidden.
In the end, the strange-looking proportions are much more likely to be a product of photography than a secret royal message. The picture remains an interesting snapshot from the beginning of their marriage, but its unusual appearance is a reminder that photographs can be deceptive. What looks mysterious at first can sometimes have a remarkably ordinary explanation.
*The Balmoral photograph is especially interesting because it captures Diana and Charles outside the highly controlled atmosphere of major royal ceremonies. Their clothing is informal, the landscape stretches behind them, and neither appears dressed for a formal portrait. Yet decades later, the image has become another example of how intensely people continue to examine photographs of the royal couple.
