Description

Very minimal processing was done. All I did was a histogram stretch to go non-linear, followed by a couple of rounds of gentle noise control using ACDNR, then one round of HDR Multiscale Transform. That's it! No saturation. No sharpening. Nothing else was done to it. Did not even use DBE or Background Neutralization, which almost everyone agrees should be done at some point in the work flow. I just found that no matter what I did, I couldn't beat the original data.

Now I will say that I drizzled to 2x and then resampled down by 1/2. This has become a new standard to my workflow and gives some excellent noise control benefits.

I am still learning how to use Deconvolution, and I want to do that before I resample down by 1/2, but I'm going to have to revisit this image again later when I learn how to do it properly.
