Fort Constitution Bunker
Fort Constitution, New Castle Island, NH - USA
Here is an example of exactly why HDR (High Dynamic Range) photography is so cool. This shot would be nearly impossible without HDR or some other kind of multiple exposure editing. The reason being that there is no way to have the dark inside of the bunker exposed properly at the same time as the lighter scene out the window. When you are physically standing in the bunker your eye is able to process all of the light information in a way that a camera lens simply cannot do in one exposure... If you will allow me to wax nerdy for a second here, the scientific explanation is basically that the human eye can see about 11-24 "stops" of light and is intelligent when it comes to viewing a dynamic range of light. On the other hand, a camera can see about 3 stops of light in a single frame (though RAW files hold more light info). Basically this means to get the same amount of light with a camera you’ll need to take multiple photos of a scene, all at different exposures, so you get the full range of light. Then by combining them you can recreate what you see on scene! This is the main purpose of HDR in a
Anyway, this fort is a cool place to walk around, but it is still an active military base, so be sure to follow the white footpaths!
