The clouds do not actually clip much in the RGB histogram or image, but the levels are so compressed in the upper highlights to get the clouds under "255" that it is posterization city if you try to recover cloud detail from this, because the level of noise is too low to prevent posterization.
But experience certainly also matters in photography, don’t you agree? I don’t mean how good you are, but things such as observing the effects of aperture and diffraction in the subjects you shoot.
Science does not tell you to drive at 55MPH. Science tells you that on level ground, a sustained 55MPH uses the least amount of fuel per mile. It does not tell you that driving in the city and rapidly accelerating after stoplights and stop signs, and also rapidly decelerating when approaching them, peaking at 55MPH in between, will improve your efficiency. It does not tell you to take a much longer route by highway at 55MPH will use less fuel than a much shorter route where you can only drive 30MPH.
I fell for the efficiency fallacy, emotionally, if not rationally when I retired. When I worked, my drive had a lot of highway miles, and so I averaged about 28MPG when I was working, but when I retired, most of my driving was through stoplights and stop signs on local streets, and it dropped to 17MPG. That made me feel that I lost something, but I did not. I drove a lot less, and used less fuel, total.
The Canons don’t have blinkies at all until after you’ve taken the photo. And I understand that this is perfectly fine under most conditions, but not when light is changing constantly.
I think you'll find that manufacturers with a bit of video history/involvement are much more likely to include features/tools that help with setting good exposure.
So what point are you attempting to make? The content cannot be verified, so who knows where it came from and how it was created, especially since you have a history of faking images to suit the agenda you are pushing at the time.
