Thanks! I think it would take me a lot longer than a heartbeat to remove the chandelier but I'll give it a go when I have some time.
It's a three-shot vertical stitch, 5D2 in landscape orientation, hand-held, 24-105 zoom at 80mm. The only post-processing, apart from the usual tweaking in Lightroom, was using the vertical lines tool in Autopano Pro.
Looking at it now, I wish I'd moved just a fraction to my right, to avoid the vertical bright line in the doorway. Should I remove it, do you think? (it would be easier to deal with than the chandelier!).
The Château de Versailles is a pretty big house, yes. Louis XIV was jealous of his finance minster's shack and ordered something "100 times bigger": 700 rooms, 69 staircases, etc, etc (no bathrooms, which apparently made the odours less than entirely pleasant but didn't prevent a prodigious amount of bed-hopping). There are vast quantities of gilt. It is perhaps the archetypal monument to the triumph of money over taste, but even so, it has the odd quietly beautiful area: this one is off the main entrance hall. Parts of the gardens are very pretty.
One tip: don't even think of making the mistake I made by visiting the place in August. Very hot and far, far too many people.
