Sunrise Bejing style HDR

This is a true HDR clip,540 images bracketing exposed +/-1 for a total of 540.Manually stacked 3by 3 to have a total of 180 HDR images (long post-production).Here I used a kind of Bejing-doom -post bomb look.There are some artifacts but it is just an experiment on a normal sunrise sequence.Close to the end on the upper right corner you can see a balloon,you see 3 but it is the HDR stack,the balloon was just one.Enjoy
