I like pictures that behave almost as graphics. In this photo, I deliberately underexposed the image to take the shadows down to black. This effectively renders the barn as a shape instead of an object.
Every detail doesn't always need to be shown for a photo to be effective. When I first started processing my images, I instinctively wanted to open up the shadows to show more detail. I still do that in many cases, but in a scene where I want to focus on shapes or lines, making detail disappear in the shadows is a great way to generate that focus.
