Understanding high-dynamic range (HDR)

Any scene that you look at has a dynamic range; that is, it has a range of brightness. One of the things that complicates the photographic process is that your eye can perceive a much wider dynamic range than your camera can. That is, it can see a much greater range of dark to light. So while your eye might be able to see details in bright highlights, and dark shadows within your scene, your camera will only be able to see detail in one or the other. In high dynamic range imaging, or HDR, you shoot multiple frames, each exposed to capture a different part of the dynamic range, and then you use special software to combine these multiple images into a single final image that has detail across all of its highlights and shadows. Your camera has the ability to shoot and merge HDR images automatically in camera. I've got a scene with a good amount of dynamic range here. I've got a dark projector over there. I've got those bright flowers back there. Watch what happens if I just take a shot…
