HDR Photography

Notes on HDR (high dynamic range) photography used to produce some of the photo's in our company calendar. HDR is a technique that allows a greater dynamic range of luminance between the photo's highlights and shadow detail.The photo contains three different exposures. One shot is "normal" another is over exposed by two f-stops and the final is under exposed by two f-stops. This is also known as bracketing. The images are then combined in Adobe Photoshop or a HDR program such as Photomatix. This wide dynamic range allows HDR images to more accurately represent the range of intensity found in real scenes.
