High Dynamic Range Photography

HDR photography allows for a greater range of brightness and contrasts. The human eye sees a vast range of dark to light, but when using a Light Capturer, we must choose a much smaller range to expose. In order to expand this range, HDR takes three photographs quickly in succession. One under exposed, one over exposed, and one regularly exposed. The idea of using multiple exposures in order to create an image with a greater range of luminances has been around since 1850. Only with the advent of digital photography has the process become practical. Using new software, the three files combine into one. Through a process called tone mapping, the artist selects information to be removed in order to make the image viewable and printable. Sometimes, the result is more accurate than a standard photograph. Other times, the photograph resembles a painting or a comic book image.
