True. The right use of various 'standard' adjustments may well get the same results as Tonemapping.
I don't buy the 'xxx' software gives the most natural results. I would suggest most, if not all, HDR/Tonemapping software can give natural results. It's just a matter of careful use of the various adjustments.
For what it's worth, except for the sun in the photo, I wouldn't know that the OP's photo is an HDR photo. In this picture I actually like the strong local contrast, including the contrast in the sky.
Some people associate "the HDR look" with excessively
low local contrast in the result. This picture has high local contrast, and it's very well done with little hint of the usual halos and other artifacts.
To the OP: What is it that you don't like about the software or the results? What are you trying to achieve by changing?
