It was basically dark out, when we began shooting. However I had my tripod, and 2 Canon 580ex flashes with me.
So I set the shutter speed to 30 seconds and ran like a mad man flashing different parts of the house. Helen the real estate agent helped. It took 3 tries but we ended up with a pretty good product. You can still see my shadow in the middle garage. I kinda like that, its like a signature. =)
