This was really intriguing and I did my own tests as well! Thanks for sharing this. I found that this is definitely ideal if you can control the level of the scene pretty easily. However, when you have a naturally very contrasty image with bright highlights, and you have to exposure as to not clip those, if it brings your subject to a place where they can't be exposed higher, it will not be as clean. Particularly in low light situations as well. It will be super noisy overall if you shoot in high ISO and you can't get your subject to be well exposed to the right. So pairing a well lit scene with high ISO and ND to stop down as need, shooting at 3200 was the cleanest in my findings! And shooting at 400 iso was cleanest with low light (I'm talking middle of the night with only a literal medieval torch lighting my subject) but obviously I'm accepting that I will have no detail in my dark dark portions of the image, but it's better than the noise of shooting high ISO to me. All very surprising, and really changed what I always assumed which was to just shoot in the lowest ISO possible for any situation lol

You are losing dynamic range though stepping up to the next iso range. At least based of cineds review.
How can noise be judged by overexposing the image? The exposure should be the same for all iso
No video just photo noise comparison?
