ISO 200, f/1.8, 1/2000, portrait.....what's the point of 200 ISO?

If you're exposing the photo properly, I don't see how ISO 200 would yield any better shadow detail than ISO 100 (that's assuming that you're adjusting your aperture or shutter speed 1 stop to compensate for the increased ISO). On the other hand, if the higher ISO is being used to ETTR and the shutter speed and aperture are not being used to fully compensate for the higher ISO, then I think there is validity to the idea of maintaining better shadow detail. When in bright sun, it's often possible to ETTR by adjusting either aperture or shutter speed without the need to boost ISO. From my understanding, simply shooting at a higher ISO and compensating with the aperture or shutter speed is not going to yield any better shadow results. Thoughts?

I'll admit, I tend to be from the "old school" of digital photography, where ISO 100 was the "default" ror good quality photos, but this assumed that you could get a great exposure, but for the shadows as well, including a proper shutter speed and aperture, all so that you could get a good shot!

Since I wanted good shadow details, I have tended to "ETTR" (Expose To The Right) anyway...

So, if I were shooting on a bright, sun-shiny day, I'd set the exposure of the bright blue sky at +1 EV, light, but it was a good setting for a variety of shades.

And then, speaking of variety, you had to work with your other settings, including the ISO speed! If you had action, then ISO 100 wasn't enough!

Here are a couple pics where I was cranked up to ISO 400, and was still lucky:

I'd be more concerned about a depth of field insufficient to get the entire head in focus at this f-stop. Unless it's on a crop sensor or not a close up portrait, I need about f/5.6 for a good one.

I was shooting some helicopters today, and wanted to slow things down to get prop blur.
This was on my 7D2.

I dropped the ISO as far as it would go and BAM, 200 was it. I had some custom function enabled that required auto ISO shifting (tone priority maybe) and had no time to dive into menus.

So up went aperture to like f/22.

Anyway, not a portrait setting, but sometimes your sort of stuck with no ISO 100 :)

ISO 200 on canon could be highlite protection enabled.

That pushes ISO to 200, but effectively exposes as ISO 100, so the highlites are less clipped.

Is that the mythical ISO 2oo?
