This statement is not meant for or against any royal person. I am just on this particular topic as I have this thought... I wonder if some of the times we see royals looking at the camera it could be because they perhaps hear the noise of the camera? Many photographers still use cameras that make noise as they click away and so forth. Just wondering if some ladies hear these noises and instinctively look up or in their direction?
Not the "clicking" sound (which on old cameras was the sound of the shutter, but these days of digital cameras that just imitate the sound to make us feel better
) but often its more that the photographers are calling the persons name to get their attention. A photographers meal-ticket is a money shot, a full face on photo, especially when its the paps. A seasoned professional can block out this, and focus on the task at hand.... a brief acknowledgement of the photographers, then look at the people you are there to meet etc.
A true camera whore stays too long at the photo call, and loves the attention of the throng calling their name.
