What is High Dynamic Range?
Put simply it is an advanced method of recording images, which documents as much detail in areas of deep shadow as those in bright light. With HDR a true photographic reproduction of any image or scene may be possible. Currently, a camera records an image, either to a memory card or film medium. The image is processed across electronic platforms or in a laboratory, edited if necessary and then printed on photographic paper. Unfortunately, the technologies at work are not always equal to one another and any inferior part of the process will affect the entire photographic system. HDR will work in this way as well, affecting cameras and memory as well as printing processes and software applications. Currently digital images are saved in either the JPEG or GIF formats, and neither presents enough range for an HDR image because instead of a color range of 0-255, HDR climbs into the millions. This means that 8-bit technology will require an expansion to 16-bit in order to accommodate the eno
