1104 - HDR photo of State Street, Madison, taken form the Capitol. This photo was taken after a large snowfall, onthe same evening that I took the photos of the Capitol with the yellow and green colors. 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.
