This is one of those situations where it's impossible to get what you want with one shot - the interior of the space was very dark, and it was a really sunny day. So either the windows were blown completely out, and you could see wood, or you could see through the windows and the interior is completely dark.
A photographer has a number of ways to solve something like this, depending upon the number and type of toys at their disposal.
One way would be to have an external flash inside the barn,
and set exposure for the scene outside the windows.
I don't have one of those.
Another way could be to set up on a tripod and take multiple shots HDR style, that will meld seamlessly together.
Didn't have that, either.
While I'm generally a minimalist, I wasn't there to take pictures - I was at this location to do lighting for a commercial, not run around with my still camera, so no tripod.
I couldn't get the idea out of my head though.
So I took a couple of handheld shots at different exposures and mashed them together to the best of my abilities.
(I don't recommend this method if you have a better option, and I'll spare you the number of hours and explecitives it took to get those %&$^ window frames to line up from different angles.)
Considering the lack of forethought on my part, the final product isn't so bad.
