1102 - HDR photo of the Madison Capitol with a green and yellow dome. The dome was lit green and yellow to celebrate the Packers Superbowl victory. This photo was taken after a large snowfall. An HDR (High Dynamic Range) photo involves taking multiple photos at different exposures, and then combining them using special software (here I am using Photomatix Pro). An HDR image allows you to see detail in both the very light and very dark areas of the photgraph.
