Uses for HDR Photography

Many times when making a photograph, we shoot a photo +/- one stop (or more) to be sure we get a reasonably close approximation for the
correct exposure. We then select the one that more closely approximates what the mind remembers, that which the eye saw. In a way, this is a type of manipulation of the photograph. A secondary
software manipulation could be (a) sharpening a slightly out-of-focus photo, (b) adjusting the endpoints of white and black to produce purer whites and blacks (levels), (c) increasing the saturation on a cloudy day to increase the level of color intensity to a remembered level, (d) etc., etc.
Occasionally we make a photo of something that has a dynamic range of light to dark that the camera is not capable of capturing in one photo. The eye may be perfectly satisfied with what it saw and a picture is burned into the mind. We view the produced photo and say, "this is not what I saw or remember". Enter the fairly new software, HDR (high dynamic range) manipulation.
There are a lot pf web sites which discuss the use of HDR which was initially developed for the purpose of taking 3 or more exposures and combining them to produce one photo. i.e. expose for the sky, expose for the mid-tones, expose for the shadows.
For the intent of this demonstration, I am only concerned with taking a single frame photo (which may be unusable or just not what I expected or remember) and turning it into a photo which more closely approximates what I remember. It may not be perfect, but is acceptable for a photo album, a trip reminder, a special scene or occasion.
Please leave a comment and your thoughts. I am really interested.
Following are 4 examples of such photos.
What would you have done to the original?
Remember, the final or manipulated photo can't be compared to a photograph taken in good lighting conditions with a normal dynamic range and in most cases won't resemble one.
Fog

Original

Corrected in order to
increase sky contrast and see detail in the foreground,
Misting Rain
Original

Corrected in order to increase contrast.
I did lose some of the effect of impending rain,
but gained color and detail in the fence row.
(I will probably go back and work on a compromise for this).
Finger Mountain AreaNorth of the Arctic circle
Original

Corrected in order to
decrease the dynamic range and
bring out the color and texture of these beautiful rocks
Clouds Rising
Original
(An acceptable photo to emphasize the sky)

Corrected in order to
bring out detail and color in the foreground and cliffs.
It also shows the side lighting.
All of the photos are of scenes which had some special interest to us,
rather than just capturing a nice photograph
