So above you say "ISO doesn't change the amount of light the sensor collects"...

and now you are saying "ISO does change the amount of light the sensor collect"?

I'm sorry, what don't you get that while the sensor captures the the same amount of light at higher ISO

Now you are back to agreeing that ISO does not affect the amount of light the sensor captures/records

Again. Really. You can capture it but as there is no way whatever to see it it's pointless.

As ISO increases you capture less light in the Real World.

No....A factually inaccurate statement. Try it. Blank wall lit by constant artificial light. Set camera on tripod at f2 and 1/60s in MANUAL EXPOSURE mode (Shoot RAW). Notice that regardless of what ISO setting you select...the sensor never captures more or less light. You can open the files in RawDigger and confirm the amount of light captured did not changes you increase ISO setting

Really not, as the ISO amplifier blows the data off the top of the range AND IT ISN'T IN the Raw file!!!

Only time you "blow out the data" (exceed full well capacity) and can't use it is if you set shutter speed and/or aperture so full well capacity gets exceeded. ISO doesn't not play a part in what the camera sensor actually captures/records

BUT as ISO increases you cannot, in any way, see what was captured so it is no use to photography.

Not true....Many of use often shoot RAW in an ISO-less ETTR workflow (often using UniWB) from time to time. Pretty easy to access all the data

Shooting ISO-invariant for any ISO below 800 will just be a noise-fest on off-sensor ADC Canon cameras. That isn't what the OP wanted.

But again....it shows ISO does not have any affect on how much light the sensor actually captures

Okay, we're getting nowhere, it's no use to the OP and I don't see anything I've said that I don't think is correct, so how about we all go get a coffee. BTW do you disagree with the cameras I suggested for them?
