Welcome Ken, glad to see you here!
Right now I'm working on a first processing example, including histograms and curves transforms, as well as wavelet and SGBNR noise reduction procedures. It is a fully worked, step by step example that I hope will clarify things a lot. I'll include also a raw image and processing icons ready to reproduce the whole thing.
I should have this ready in a couple of days. In the meanwhile, please shoot me with any questions you may have.
Of course I know processing examples are essential; just have a bit more patience ... :wink:
Best,
Juan
