HDR technology allows us to see the world as we have not seen it yet.HDR – the abbreviation stands for High Dynamic Range, ie, “high dynamic range.” And tucked behind her bright, rich, stunning images – these colors do not see any on regular digital photos, or even on film. HDR photography can be even brighter than the reality, accessible to the human eye. The term “dynamic range” refers to the maximum difference in brightness, which is able to fix the optical device – a normal camera, digital camera or eye.Everyone knows that at the entrance to the sunny street into a dark room, his eyes have become accustomed to begin to distinguish between objects at dusk. And the bright sun, we would not notice the object lying in the shade. This is a manifestation of our limited “dynamic range”: the eye (and handles it signals to the brain) can not simultaneously perceive and lit, and shaded sites. Just limited – even tougher – and the usual digital photography. But modern technology allows to circumvent this restriction and see the world as we’ve ever seen. HDR-picture – this is a picture where there are no black spots or white, it is all saturated.
How do photographers get a brighter picture, if the restrictions remain the same equipment? Very simple: a static object is photographed, the camera is mounted on a tripod, and made several shots with different settings. For example, three: normal, too light and too dark. The resulting files are loaded into a special program – and here received HDR-file.
