This. Unless they’ve spent their entire life in a cave, everyone knows that there have always been ‘tweaks’ to paintings / photographs etc.
It’s just that we expected the RF to be trustworthy (because that’s the public image they’ve been pushing for literally centuries - since Queen Victoria) and to, at worst, polish up their photos.
If they have been faking them entirely, that’s a big deal. If they’ve been doing so to hide serious issues, that’s an even bigger deal.
I have no idea if they have been. I’m absolutely not in the confidence of the Royals.
If the photos (Mother’s Day and Queen with great-grandchildren) are genuine (and I think they may well be), the RF could apparently prove this by showing the originals (not necessarily to the public - showing them to chosen experts would do). They haven’t and that’s why the issue rumbles on.
It probably is just inept PR (possibly because Kate does at least contribute to the RF PR strategy and she’s not well enough at the moment) but the Palaces don’t normally leave this sort of space for conspiracy theories to flourish.
