High Dynamic Range (HDR) Photography is created by taking several photographs of the same subject with different exposure values. The same aperture should be used for each of the photographs to ensure the depth of field in each image remains. If you take 3 photographs, 1 should be correct exposure, 1 over exposed and 1 under exposed. Combined, these photographs contain detail in both the shadows and the highlights. By using software such as Adobe Photoshop or Photomatix Pro, a single image can be created using all this information. Some of the images in the gallery below show the image taken at correct exposure followed by the HDR image.
