Good experiment and anticipated results. As noted, this does not apply to RAW files, as you have shown. This is an acceptable approach for folks who don't wish to shoot RAW format.

The potentially better method is the application of ETTR/ETBR techniques. In processing the image, the shadow areas can be darkened to the desired level, as opposed to the need to brighten them. Thus, ETTR/EBTR, as a side effect, masks noise better in the process of exposing/processing.

Canon's version is called Auto Lighting Optimizer. Sony calls it Dynamic Range option, D-Range or DRO. Other manufacturers probably offer it with different names.

To find out what it does I did a simple experiment. I put a diaper, a dark robe and a gray card in full sunlight and did a series of exposures with my D610 on Manual at ISO 400, 1/1000 sec @ f/11 and looked at the histograms with RawDigger. The raw histograms were virtually identical. The right end of the green histogram fell into the 8000 to 16000 range which means that one more stop of exposure and the highlights would have been blown.

On the camera, each of the color histograms was touching the right end of the scale. As I progressed from Off to Low, Normal, High and Extra High the left end of the histogram moved to the right and the shadows got brighter. For High and Extra High there were some blinkies flashing.

For Nikon, it appears to do shadow recovery somewhat like you might do when developing from a raw file. I will have to repeat the test with my A7 II but I expect similar results.

Exhibits are in the next post.

My cards are camera specific. I do format them in the camera in which they are intended, after transferring the files to hard drives and verifying that the files transferred error free.

I was updating software for my D810 and D500 with a card. I used it an erased the stuff on there after using (the updates). My question is, if I have formatted a card in my D810, and then decide I want to use it in a different camera, the D500 or even the Canon I have, does it matter? I usually don't format cards to begin with, I just stick them in the camera and they work fine.

I shot this Lion at the Arizona Wildlife Zoo near Phoenix through a chain-link fence (tricky).
Hand held @ 800mm. Distance was about 60-75 feet away for the Lion.

Canon 5Dsr - Canon 400 II DO f4 - Canon 2x III - 1/80 - f/8 - ISO @ 250.

Nice work, Bill. The cold weather doesn't seem to bother your subjects. So, good to take advantage of that.

gvarber, DaveC1, and Erickter, thank you all for stopping by and commenting.
Dave, nothing like film in 35mm or 4x5 either. I'm off to shoot some large format in a few minutes.

Bob, I hope, as I did, you avoided any trolls living under the bridge.

I agree with lesdmd in that using the whiz bang push button approach to making your photograph yours, is not always the best path to take. Compositionally, the subject is too centered. I'd prefer the subject to be a bit to the right of the photo looking towards the center. Additionally, a bit more separation of the darks and lights would bring the subject out a bit more.

My buddy on his perch watching over his 2 Basset sisters as they roam the yard. First attempt at using filters in LR. Usually just adjust exposure and noise. Not thrilled so any tips would be appreciated

When I first saw the title of your post, I thought....what could be so great about a water treatment facility? Well, now I know! Fantastic shot. The manager should be hanging it in his office. Very nice work!
