Taken in Carlsbad Caverns National Park, New Mexico. This shot was hand-held at 1/20 sec, f 4.0, ISO 4000. The lighting is provided by fixed artificial lights and sadly the highlights were a little blown. I found that I could recover the details in the shadows better with Topaz than Lightroom, but I have some more ideas and I might work more on the image in the future.
The work was all done in Topaz Studio, with BW providing a lot of the recovery, then precision contrast, then precision details, then denoise, then duotone.
