"The Red Floor"
Bill Geoghegan

Nikon D90
Nikkor 18-200mm at 24mm
1/60 sec at f/16
ISO 3200

Bill Geoghegan took this image on the "Red Floor" of the Seattle Public Library. Circumstances dictated a handheld shot without flash, and the small aperture was required for adequate DOF. The high ISO led to considerable noise, corrected in post using Lightroom 5 with Nik and Topaz plug-ins.
