What a sight! Gigantic, huge, beautiful, elaborate, amazing - these words don't even begin to describe it.
Here's a view from a little lower:

That gives it some perspective.
Now for some more:

Can you imagine...?
I've said it before, and I'll say it again - lighting these gargantuan homes would take a lifetime. Use the ambient light, bracket 7 frames, and post-process. Either that or spend your day (and lots of money) playing with lights.
The other half of it is knowing how to post-process correctly. Don't overdo it. The goal here isn't to make something look fake/HDR-like, it's to make it look real. If you've done any research into HDR, you know that the human eye can observe a much greater dynamic range than your camera. So you walk into a home like this and your eyes can adjust for the windows, for the shadows, for the mid-tones, for the overall tone of the space in an instant. Our cameras don't have that luxury - they expose for grey (18% I believe). If you are in evaluative/matrix metering, your camera meters the whole frame and exposes accordingly - most of the time, the highlights coming from windows throw the metering out of whack and send the rest of the space into darkness. The camera thinks it did a good job, believe it or not.
I'll be writing a much more in-depth critique of Exposure-Fusion/Exposure Blending vs HDR in an upcoming post, so stay tuned. Oh, and the critique won't feature math, benchmarks, noise ratios, or any of that other 'junk' - it'll be a comparison of images. Imagine that.
