Took a recent set of pictures of the Henry Clay iron furnace at Coopers Rock State Park. This isn't quite an HDR shot. Rather, it was created with an Adobe Lightroom plugin called LR/Enfuse.
LR/Enfuse does a nice little trick with a number of bracketed shots, creating a well-balanced lighting effect without the intensity of a high dynamic range picture.
While shooting there, I met a photographer from Pittsburgh, who was also shooting the furnace. We swapped lenses, so I got to try his Tamron 28-80 mm lens.
I learned that this opening has a special name -- it's called a tuyere. That's the name for an entry through which the blast of air enters a furnace. If you're interested, here's where I got my old iron furnace anatomy lesson: http://www.oldindustry.org/OH_HTML/OH_Buckeye.html#Description.
