Re: Exposure compensation and Highlight weighted metering

ISO doesn't affect the exposure I set because I first set aperture and shutter speed the way I described before.

In you method, auto ISO setting obviously doesn't affect you exposure settings. However it limits the max possible exposure. That means, if the camera metering makes a mistake, you're at a higher risk of blowing the highlights. Otherwise it's a good method for the cases where the aperture and shutter speed have a higher priority than ISO. It's  good mostly in action shooting in my opinion, but it can be used in other scenarious.

If I still have highlight headroom I raise ISO because reducing the read noise is more important to me than dynamic range.

I use similar approach for night photography, only without auto ISO. Only when ISO is in so called ISO-invariant range, this method stops working, you just reduce the DR without improving the noise.
