This is an abstract image of a detail on an old, rusty boiler left outside the Oil Creek Mine on Pikes Peak. Miners dug a tunnel into the side of the mountain in hopes of finding gold or silver, and they struck water. They had to stop digging, and the water coming out became a source for Manitou Springs or Colorado Springs. Water still flows here, and the tunnel is gated, but some of the equipment remains.
I always tell my photography students that when they have an image with uniform color they should convert it to black and white, which then allows the viewer to better see the textures, shadows and highlights. The color becomes a distraction, and the absence of it brings the photo to life. That is the case with this picture.
I went a little crazy with the clarity, shadows and contrast sliders in Adobe Camera Raw to bring out the texture in the rust. In Photoshop I used the Spot Healing Brush to remove some bright spots. I added curves and black & white adjustment layers before cropping.
