What is HDR

HDR stands for High Dynamic Range. Several photos are shot at varying exposures. One at normal, another at 1 stop above normal and another 1 stop below normal. The there can be more exposures also to make it more interesting or more bazaar. These photos are all sandwiched into one photo. You may have seen something like this in whatever media you visit. Here is an example. https://www.facebook.com/photo.php?fbid=309313035774132&set=a.252586238113479.59369.177656418939795&type=1&theater
