I'm afraid you are still missing the point. If you're testing ISO6400 performance and finding that highlights are clipping then of course you have to reduce exposure.

it is you who is missing the point. it is well arguable that both shots got the right brightness - the sky is black and the walls is lit. the fact that inside the building detail preserved is a bonus. reduce ISO to 100 without any in-computer brightening (which is what you are advocating) would give you detail in the building but no details at all on the walls.

Put it this way, did the poster do all he possibly can to preserve highlights when using high ISO? If he did not then I don't know why he's complaining about lost highlight detail. When it comes to lowlight shooting, highlights are much easier to preserve than deep shadows.

When high iso is chosen by the metering system, it is never about high light preservation, it is about overall brightness of the resulting jpeg having "proper brightness" - which is 18% grey.

What you are saying is that people shouldn't do that, they should save highlight using lower iso and brighten the image in processing - that is exactly what "shoot low iso then brighten in post" is all about. You understand the need, obviously. But you insist on arguing otherwise with this thread merely because other people have said it first. It seems narcissistic to me.
