>>4475776>Auto ISO on Aperture PriorityIs arguably the best general purpose do-all automated mode, that most everyone could use and be fine for 95% of situations. I see enough of the marginal benefit from avoiding Auto ISO altogether though. If I'm letting ISO control for exposure, I'd rather just underexpose and do that control in post.
Not sure why your mentioning exposure compensation, that just shifts where the meter thinks is 0, it doesn't change behavior of auto ISO / SS. EC just says "instead of going ISO/SS up/down at X brightness, go up/down at Y brightness instead". The behavior stays the same.
>once you need more exposure but you exhaust first the minimum SS limit, second the max ISODepends on the camera. If you are in situations where you are frequently hitting the ISS or ISO limit, that is all the more reason to switch over to more manual control.
If you've ever unintentionally clipped your highlights, with an ISO above your cameras minimum, that's a prime example of Auto ISO screwing you over.
If you've ever shot a series in quick succession, but the cameras exposure varied (even slightly like 1/3 of a stop), that's an example of Auto ISO screwing you over.
Knowing what settings to use / how to expose an image the way you want, is the easiest part of photography. In many situations, you can go literally hours of shooting without ever needing to change your settings if set properly. Use whatever works best for you.
