Both you and the Duck are correct. It all boils down to what type of
image the photographer is looking to make. I use auto ISO when I want
to use a fixed shutter speed, and a fixed aperture. As for setting an
upper limit, there are times when a really noisy image is preferable
to no image at all. I would very much prefer a very noisy and grainy
image of the abominable snow man, to no image at all.


I've set my Canons to ISO 200 and keep it there* as I want the feedback
from aperture or shutter speed telling me when I am on the edge of
insufficient light.

* There are some exceptions!

Most of us have different photographic interests. I use auto ISO
primarily for high speed sync, and some landscape. i consider auto ISO
only as another tool which I use mostly to get a desired effect. some
use auto ISO for panos.When it comes to photo art, i think that the
image maker should use tools that he is comfortable using. And if he has
the interest, see if an alternative method would produce a result closer
to the result the maker seeks. Several weeks ago I started working on an
image about 9:30 AM. I just couldn't get quite the look I wanted. I kept
trying different tools. I finally got a bit hungry, and walked away from
the computer. It was after 11:00 PM.
