M31, the Andromeda Galaxy, in a series of exposures to test stacking images with HDR techniques. I shot the galaxy in a series of 1, 2, 4, and 8 minute exposures, four of each exposure, all using the Nikon D750 and 92mm TMB refractor. A set of 1,2,4, and 8 minute exposures was stacked in Camera Raw using its HDR mode to create a new merged DNG file. I did this for four sets of 1 to 8 minute exposures, then processed each of the HDR stacks with Shadows and Highlights in ACR to bring out faint detail but retain detail in the bright core. Each of the 4 HDR stacks was then mean combined stacked in Photoshop and processed with Curves, S&H, B&C etc. So in total . (Photo by: Alan Dyer /VW PICS/UIG)
