>>3827507>not blowing out the highlights with almost directly above sunlight with giant windows everywhere and keeping the foreground well lit.Hey, uh, I'm also a Fuji shooter, so I'm not attacking you for that, but you're definitely doing that wrong.
In terms of how you want to expose for your highlights, your ISO and shutter speed do the same thing--it's not like raising your shutter speed keeps the highlights from blowing out and then raising your ISO keeps the foreground from being too dark. If you move them both the same number of stops, all it does is keeps the same overall exposure.
At least, that's what would happen in a perfect world where changing ISO and shutter speed didn't affect anything else, but what you're ACTUALLY doing is the OPPOSITE of what you're claiming--shooting at high ISOs lowers your dynamic range, so the difference between the darkest parts of the image where you can still make out an image and the brightest parts gets smaller. If you'd shot at base ISO with a 1/160th shutter speed, you'd have MORE info in the highlights and MORE info in the shadows for your final image, not less.
The only valid reason to go with an ISO that high when you have plenty of headroom for a fast shutter is if you deliberately want to make the image grainy and noisy. Which can be a legitimate artistic choice if that's what you're going for, but that's not what you're claiming you're going for, which means you're just not doing it right.
