ETTR does not mean you need to increase the exposure

Not just irrelevant, it never existed. ERADR was a figment of someone's imagination.
The entire concept was based on looking at JPEG histograms in editors without seeing the raw histograms.
No ERADR means there is no EBTR without blowing the raw highlights. There is plenty of evidence of that happening today.
Much of what has been posted on UHH about ETTR has been misinformation and obfuscation.
It's not that modern sensors behave differently. They have behaved this way all along. We just needed to compare the JPEG histograms to the raw histograms to see how they worked.

If your shooting mirrorless, you will be able to see the effect of your exposure prior to tripping the shutter.

I adore my Sony which meters for highlights, with customizable zebras to indicate levels over 100 IRE...

Exactly!!!

The developed file could use a boost of the midtones. You can do this adjustment very easily by use of the Levels Adjustment tool. Set the Blending Mode to Luminosity (to avoid a color shift). Move the midtone slider to the right to bring up the midtones to eye.

I like to think I use ETTR but not necessarily always to the nth degree, trying to get every last tiny fraction of an f stop. I try to make sure the histogram is pushed toward the right but not to the point that I'm concerned that I might have accidently overdone it. Maybe the safest way is to use exposure compensation to take the histogram to the right, then use bracketing up and down in 0.3 stop steps from there, and then pick the best one in post.

Even my A7 II where Zebras show up more than a stop below the raw limit is reliable.
Newer Sony models have made the Zebras even better. They get closer to the raw limit.
The Zebras (and blinkies) are the easiest tool to use if you feel you want to use ETTR.
The Z7 only provides Zebra warnings for video but it has the next best option, highlight weighted metering.

I spent very little effort on this image since I was only interested in demonstrating the concept.
But you are right. Even at ISO 400 the D610 has so much DR available that you could do a lot developing from the raw data without screwing things up.
If I needed more DR I would have used base ISO which is really the only ISO anyone should be using if they want to take advantage of ETTR.

And there is nothing wrong in using Sunny 16 as you did in the first image in Abandoned Omaha building.
It may not be ETTR but since you were at ISO 100 ETTR would not have made it any better.

Yes, I have been alluding to this for some time now ....

There are plenty of low DR scenes where ETTR provides no benefits at all.
Here is a simple example.

This is what it would have looked like with 2.5 stops more exposure to make it ETTR

The only edit was an auto-adjustment to the luminance range

ETTR which stands for "Exposure To The Right" certainly doesn't mean increase exposure. That's all!.

Most of us know that.
But the promoters of ETTR on UHH don't recognize that simple concept. In every example they post the exposure is increased.

Even when you use Sunny 16 and it ends up short of ETTR there is often enough DR in the raw file to recover the shadows.
This scene had just over 7 stops of DR.
Sunny 16 SOOC - 1.5 stops darker than ETTR
