In its true form yes but with many different photographic software programs you can, as I did.
Of course we can make HDR images from one shot. The point of HDR is to compress the High Dynamic Range of the image/images onto the low dynamic range of the monitor or printing paper. The best monitors can display maybe 10 stops in ideal conditions and a paper print maybe 5 to 6 stops.
Current cameras have 13-14 stops of DR. To show all of that some kind of HDR mapping might be handy. In the past cameras had so low a DR that several images were necessary, perhaps 5 or 7 images shot at one stop intervals. Now I would not do more than two images, one at -1 and one at +1 stops of exposure compensation. This will yield a whopping 16 stops of DR. Most HDR mapping software will have trouble mapping that into anything that resembles a photograph in a credible way.
Your example has lifted the shadows nicely and compressed the highlights making the clouds visible. The mapping looks good to my eyes, but what I do not like at all is the clarity setting that's way too high.
Too strong a clarity setting makes the image look like a cartoon. There are a lot of HDR images all over the web, some in this forum too, where the clarity is pushed through the roof and at the same time saturation is maxed out so high that it makes the viewer's eyes bleed. I don't know why people do that other than they have so severe cataract that they cannot see anything without the nuclear treatment.
Can you lower the clarity (which makes the heavy outlines/halos) but keep the shadow and highlight mapping as it is? The best HDR images are the ones where the treatment is not obvious.
