The corrugated roof of a warehouse, taken at night. For this, I had to put the ISO up to 3200, which is pretty obvious when you look at the sky. I think the noise adds something to the photo though. It makes it feel less flat and a bit of noise always seems to work with black and white. Although the roof of the warehouse is a direct black and white conversion, the sky is slightly toned so that it stands out. Fortunately, I didn’t have to add a vignette, as shooting with the lens wide open provided one for me!
