The 3 bracketed shots were merged in LRCC HDR Merge. Then it was sent to Aurora 2017 as a single layer in PSCC; some more punch was added with Macphun Intensify, Elegant Softness; and the final touches were done in ON1 Effects, HDR Look, Glow. (Note: if I have a lot of sky, I often have significant issues if I do the merge in Aurora 2017; that was not the case here. If I do have difficult problems, I cut my losses and do the merge in LRCC. You may have noticed that I consistently go through the same workflow; i.e., merge in LRCC HDR Merge; send the file into PSCC; do the major work in Aurora 2017, followed by Intensify (where I sometimes use Natural Enhance, and sometimes use Elegant Softness, and sometimes both selectively on separate Layers; and, on a rare occasion, I use Elegant very selectively); then I do some work in ON1 Effects (I really like what HDR Look, Glow, does). I generally don't mention that I use different software to get rid of stuff and of unwanted Noise; I also go in and out of ACR. I also use Topaz plug-ins a bunch; and, for certain things, Nik plug-ins.
