There's a lot of stuff I could have done if I'd had lighting equipment with me, Chris, but that day my wife had the car to take our crippled neighbor lady out for lunch and shopping so I had to bum a ride with some other people who were going out to the mansion. All I reasonably could carry was a D3 with a 24-70 on it. Both of us can think of all sorts of things we could do with unlimited time and unlimited equipment, but as I said, with something like this you take what you can get.
And Lou, I'm not sure I agree. It might be simple just to turn on the light with Photoshop, but it seems to me that to get the resulting lighted surfaces and shadows right wouldn't be simple, unless there's something new and magical in CC that I installed with the latest upgrade without realizing what I was doing -- maybe an "Auto Light Source" slider. But having said that, if you'd like to give it a try I'll put up a PSD for you to download and use for a demonstration. Might be easier than I think. I'm a lot more into shooting than post-processing.
