Bracketing at Big White - HDR and Photomatix 7
Notice the watermark - I am using a trial version of Photomatix 7. See below for the bracketing. Seven photos, ranging from +3 to -3 stops from central exposure. Used HDR software to merge. HDR stands for high dynamic range. Dynamic range is the spread between white and black, where highlights and shadows can no longer show detail. Put another way, it is the number of stops a medium has where details can be captured between light and dark values. At some point, highlights get blown out, where every value is blank, and shadows are expressed as pitch-black. Although modern sensors typically have dynamic ranges between 10 and 14, our eyes can capture differences up to 20 stops. And that's just what we can see in real life; nature can produce values much greater than that (the brightness of the sun vs the darkest point in a cave). The fact that a raw image can manage around 14 stops of detail in between highlights and shadows means that most of the ...
