Picture of the Day - 8/26/08

Many states in the midwest, northeast, and northwest have collections of covered bridges built between the mid-1800s through about the 1920s. Parke County (with the city of Rockville as the central hub) in Western Indiana claims to be the "Covered Bridge Capital of the World" with 40 local bridges. Many of these are still in use. Usually, they are named after the builder - in this case, McAllister's Bridge, which was built in 1914 and crosses the Little Raccoon Creek. It spans 126 feet and continues to be used today. This image was created from a composite of five separate images spaced apart by 1 stop of light each (one "stop" being equivalent to half or double the amount of light). This allows reproduction of detail in both the highlights and shadow areas - something a single frame is unable to capture due to limited dynamic range of the imager chip. This more closely simulates what the human eye is able to capture.

We photographed 12 bridges today!
