Speleothem Panorama, The Big Room Trail - Carlsbad Caverns National Park, Guadalupe Mountains - New Mexico - 2 October 2018 Speleothems are the structures formed in a cave by the deposition of minerals from water . . . examples would be stalactites and stalagmites. There are several named features in this view: - The Chandelier, a draperies formation at the upper left. - The Totem Pole (left of center), a 38' tall stalagmite. - The Cave Man, the large stalagmite at right. Carlsbad Caverns is a very difficult place to photograph. An interpretive sign on The Big Trail indicates there are more than 1,000 lamps and tubes which illuminate, via 19 miles of concealed wires, the caverns. While there is a project to convert all lighting to LED, there is still a wide array of incandescent, fluorescent, and mercury vapor lamps, all with different color renderings. Even with all that lighting, the cavern is very dimly lit. While your eyes will get used to the dim lighting, a camera cannot capture the wide dynamic range of illumination. The use of a flash will only cause severe shadows in the background. All of these photos capturing views in the caverns were assembled in an HDR image from 7 bracketed frames . . . I used Photomatix Pro 6.1 to assemble the final image and Nikon Capture NX2 to tweak saturation and midtones. I made no effort to precisely match colors and illumination levels in the caverns, which would likely take many days of site photography and post-processing work. My objective was simply to reveal the shapes and textures of the 'decorations', mitigate overexposure of areas around the artificial lighting, and avoid shadows.
