I'm really confused.
Seems 'we've' spent a tremendous amount of time here
talking about how critical monitor calibration is for photo
accuracy and quality, yet here folks are talking about
in-camera adjustments using the totally un-calibrated
tiny display in the camera.

What am I missing?

I don't think your missing anything; you seem to grasp it. Computer
editing as needed for those to whom image quality is important, camera
tricks for the rest. Hell, there are people out there who still think
that so-called HDR is cool!

HDR can be a useful tool. Yes there are some who like the Harry Potter
effect one gets from overdoing it. However, digital manipulation is an
art form in itself. Some like it, some don't. It depends on taste and
the particular image.
I freely admit to frequently going over the top. I kind of like surreal
stuff.

Anyway, over the top seems like the right mood for my summer twitter
header:

Then there's this cartoonish snapshot rendition:

and lastly this somewhat less extreme HDR of a Jersey Shore moment:

Here are two comparison examples of a 0 EV exposure compared with two
different HDR renderings from five exposure brackets:

...and a another single comparison of a0 EV shot against a 5 exposure
bracket
HDR:

According to my understanding, one can get a good HDR image with 3
shots. The reason we take 5 is that Nikon only does an auto increase of
one stop, and a two stop differential is all that is needed.


The important thing is to establish an increase to the highlight/shadows DR.
The size of the differential is going to be dictated by your intention. My
habit with the Nikon is to shoot a 5 shot bracket with a 1 stop interval.
That ends up as a 4 stop range, -2/-1/0/+1/+2 differential.
Now that I have the Fujifilm X-T2 I have the option to shoot brackets of 2,
3, 5, 7, or 9 frames with intervals of ±1/3 to ±3 stops in 1/3 steps.
However, I find that with the X-T2 the shadow detail recoveryfrom the RAW
files is so good that, these days I have little need to go to HDR unless I
plan to. I suspect you find the D500 to be similar in that respect.

With a single exposure that has detail lost in the shadows, one of the best
tools available is Lightroom. It is a quick and simple technique:
1: Create a virtual copy.
2: In the Develop Modual with the original adjust the *Exposure* slider to
+3.00 and with the virtual copy to -3.00.
3: Select both in the *Film Strip* and right click, select *Photo
Merge*-*HDR*.
4: This will produce a DNG which can be edited/adjusted as a 32-bit RAW file.
The range of the exposure slider will go from the normal -5/+5 to -10/+10.
All other adjustments benefit, and the result is quite subtle.

This is far less of a hassle than doing the similar thing with ACR and PS.


Since I have LR, I will compare your method, with the way I have been
doing it it ACR. When I have one image, I have been making three images,
overexposing one by two stops, and underexposing one by two stops, then
combining the three images. As has been said many times before, there
are several ways of doing things in PS 7 LR. The best way is the one
that works for you.
