Not true, one starts raising ISO when they are already aperture and shutter limited.

Bob says - "people using ISO first technique".

Ok, then I have to question as to how using the method somehow makes one think of ISO first. Its always the last result, after exposure is maximized, regardless of ones understanding of exposure.

Interesting to do a poll, see whether most photographers set the ISO first or last. My guess is first, because the camera user interface is designed that way.

Where do you believe "Auto ISO" folks will fall?

They set last, but they let the camera do it for them.

Auto ISO is set first, and forgotten. I would wager most photographers using Auto ISO fall into that category.

Auto ISO sets the ISO after the other settings have been set, same as if a photographer set them for himself.

But it is the first thing the photographer who can't do without Auto ISO sets.

You have me really baffled here. What do you mean? It can't mean he/she sets the ISO value that auto ISO chooses, so it must mean the setting of auto ISO itself, i.e., turning it on in the menu. So do you mean this is the menu item he/she goes to first and turns on before setting exposure parameters? If so, what does that have to do with Bob's statement above?

OTOH, a photographer shooting in manual mode uses manual ISO as the last resort, or may not even bother to move the ISO setting past the base ISO at all.

And what is the relevance would the word "resort" in this context? Do you mean manual-mode shooters who don't or can't use auto ISO "resort" to fixed ISO? Perhaps you might have used "grudgingly puts up with" or "holds his/her nose while applying."

I didn't get to see your response to this:

I find it easier to establish metering of the scene at the settings I would prefer to use and then decide where I want to go with it. For example, I turn on my camera (almost always set to ISO 100), set my aperture to f/2.8 in aperture priority, and being indoor with only window light, I notice 1/5s for shutter speed. At this point, I can decide what I need to do, whether use a faster lens, or if slower shutter speed is okay, or if I need to bump up the ISO.

With Auto ISO, the camera selected 1/30s, and ISO 500. So, now that I disagree with camera... I finally choose to override it. What is the point?

And so, here you have another chance, as the other thread is no more.

Oh, so that's a last resort.  Well, ok.  I guess I'm wondering why the auto ISO came into play at all.  Since you're going to set a SS based on your own needs (even to the point of "overriding" the value obtained by auto ISO), why didn't you just set the aperture and SS where you want to begin with in M mode and then let auto ISO do its job (or not, should you decide to shoot dark and brighten in processing).  You seem to be using auto ISO here ultimately as an after-the-fact thing (which is good) but making it a before-the-fact thing.

So I still don't get the relevance of either of your statements above in yellow.  But now that you've explained what you're doing, despite my not thinking it the easiest way to proceed, I'll be able to sleep better this evening.  Thanks for the clarification.
