There are three parameters that determine exposure: shutter speed, aperture, and ISO. To me, the whole concept of automatically setting two of those exposure parameters seems somewhat bizarre. Setting two parameters automatically requires the camera to read your mind on how you would like to trade off the two.  Using  "Aperture" or "Shutter" mode with auto ISO is just like using "Program" mode with fixed ISO.

I prefer to fix ISO and use aperture or shutter priority, or set ISO to automatic and set aperture and shutter manually. Am I alone in my preference? Do "professionals" use auto ISO together with aperture or shutter priority?
