I did not use any external means of lighting the shack. If you'll notice the time, it was still "morning," and the sun was to my back, lighting the face of the building. That helped with the color/lighting, but there was a fairly complex system of editing with this one, as with many of my images.
I used either Capture One and Photoshop, or DPP and Photoshop -- can't remember which I used for RAW processing, but that doesn't really matter all that much. Basically, I took a "dark" layer, and a normally exposed layer, and used the sky from the darker version. It's been about a year and a half since I made this, so intricacies are a bit hazy, but I may have used a slightly overexposed layer, too.
In any case, just with layer masks and different exposures of the RAW file, I created this in Photoshop.
That's awesome that you found this in someone else's favorites. I'd like to think I have at least "decent" stuff all the way through my gallery, from the very beginning. Hmm, I should put more of them on the front page. . .
