Blast furnace pipes at the former Homestead Steel Works in Pennsylvania.

When I saw these pipes and metal stencil labels, I knew I had to photograph them. Problem was they were about 2ft above my head and the light was fading. I bumped the cameras ISO up to 12,800 and took this shot. With a little noise reduction in Lightroom, the image is certainly usable online. I'm going to begin printing a few mid-sized test prints of images shot with high ISO's to see how well the Mark III noise translates to print.

The Homestead Steel Works, which was purchased by U.S. Steel Works in the late 1800's, closed in 1986 and the land surrounding this derelict factory is now a National Historic Landmark. The blast furnaces (above) were constructed in 1907 and are all that remain of this massive structure. 

During operation, this factory contained 450 buildings and produced 200 million tons of steel per year during its peak.
