Eva Gryk photographed this staircase in the Mark Twain House, Hartford, CT with a Nikon D90 using a tripod and cable release. This image was photographed as an HDR, 3 different exposures at 0.5sec, F3.5 and ISO 1000. The 3 images were combined in Photomatix Pro 5 and turned into a monochrome image to create a more powerful, dramatic and mysterious monochrome photograph.
