Last Fall I visited Maquoqeta Caves State Park for the first time. I was blown away by the great photo opportunities! I am just now getting around to processing some of the HDR (High Dynamic Range) sequences that I shot. I used Photomatix Pro software to process 5 images that I took at different exposure settings so I could capture the entire tonal range of the scene. Even though I am still experimenting with the software, here is one example of an image I am pleased with.
