HDR arrives for the masses

Dynamic range has been a limitation of photography since its inception. Film and digital photographers have used a number of techniques over the years (merging film negatives, dodging and burning of film, bracketing on digital cameras) to enhance the range of their photos. The historical problem of achieving High Dynamic Range (HDR) has always been the amount of time spent post-processing the images. With film, the process could take days. With digital photos, it was reduced to hours. With the introduction of HDR on the iPhone, the process takes two seconds.

Apple added HDR functionality to the iPhone with the recently released iOS 4.1 update. With a single tap of the shutter, the camera takes three photos and merges them. When shooting a stationary subject with a steady hand, the results are excellent. Otherwise, the results are mixed. I’m certainly glad the camera I have with me has it as an option.
