I visited Louvre in September just before the painting moved. Queues were several floors long, complete with videographers following brides around to get the right shot, others having gimballed footage of every moment.
The pure embarrassment to see the line finally break after two hours of queuing to rush forward, to gain that extra half metre closer, and snap snap snap... no interest in looking at the painting but a torrent of pictures/video with quick reviews to improve shots before being told NO MORE by an exasperated staffer to then rinse and repeat.
Do you actually see the Mona Lisa if there is no stabilised moody video of you pondering to prove it?
