During our visit to the tulip festival (before I broke my camera) I took a few shots of an old barn. That area is rich with them. You could spend a good bit of time on them. This particular barn wasn't in a great setting for an overall photo. So I mostly worked on isolating interesting aspects of the structure.
All shot with Nikon D7100 and Sigma 17-50 f2.8 DC.
1. Nearly an overall shot. Had to stay tight due to a lot of cars etc. in the area.
f/8 @ 36 mm, 1/640, ISO 400
2. From the opposite side.
f/8 @ 40 mm, 1/160, ISO 400
3. This one had to remain color for hopefully obvious reasons.
f/8 @ 40 mm, 1/80, ISO 400
